瑞尔科技 'SS-H' 压力开关产品说明书
“SS-H”PRESSURE SWITCH OPERATION MANUAL (4HL2/4HH2) 3/01 1.0 INTRODUCTIONThe Ruelco “SS-H” hydraulic pressure switch is a two way bleed valve which is operated by pressure acting on a piston opposing an adjustable spring force. It functions as either a normally closed or normally open valve. Pressure applied to the sense port will cause the valve to operate.The Model 4HH2 operates as a normally open valve and is called a high switch. If sense pressure acting on the piston is at normal levels, it is insufficient to overcome the spring force. The middle o-ring on the spool is positioned below the bent grooves on the bottom sleeve, thus preventing the instrument pressure from passing to the “Vent” port of the switch body. When the pressure acting on the piston becomes large enough to overcome the spring force, the spool shifts and the center o-ring moves in between the vent grooves on the bottom sleeve. Instrument pressure at the “In” port “Bleeds” into the reservoir through the “Vent” port.The pressure switch “Bleed” action is the same for Model 4HL2. For this model of operation, the switch acts as a normally closed valve and is called a low switch. When normal sense pressure is acting on the piston, the center o-ring on the spool is above the vent grooves in the top sleeve, thus preventing the instrument pressure from passing to the “Vent” port of the switch body. When the sense pressure decreases to an abnormal level, the spring force shifts the spool and the middle o-ring on the spool becomes positioned in between the vent grooves in the top sleeve. Instrument pressure at the “In” port, “Bleeds” into the reservoir through the ‘Vent” port. Changing the sense pressure value when the switch is used as either a high or low id done by altering the force of the spring, the size of the sense piston force is accomplished by turning the spring cap to increase or decrease the spring compression. The piston diameter is changed by adding or removing o-rings on the piston or changing the piston.2.0 INSTALLATIONThe “SS-H” can be panel mounted (with optional panel mount nut) or supported by piping from the sense port in either verticalor horizontal positions. If the switch is mounted horizontally, it is recommended that the small vent holes in the side of the switch body be oriented in a downward position. This will prevent any debris from accumulating in the spring cavity or above the sense piston.Proper PIPE thread sealant should be used on any pipe fittings threaded into the pressure switch ports. If stainless steel fittings are used, a sealant that will prevent galling is required. When the switch is mounted using the ½” NPT base connectionis adequately tightened, DO NOT loosen the body from the base or re-position the ports. Instead, remove the switch and re-make the ½” NPT connection.3.0 DISASSEMBLY (See Spec Sheet)Tools and materials required for proper disassembly, repair and assembly are as follows:1. 7/8”, 1” and 1-5/16” open endwrenches or two crescent wrenchesof adequate size.2. Smallpliers.3. For switches using ¼” diameterpiston, 1 ¼” open end wrench or asuitable crescent wrench.4. High quality silicone base lubricant.5. An appropriate safety solvent.3.1 PARTIALDISASSEMBLYA) SpringRemoval3.1.1 If the switch is installed in anoperating instrument system, it is notnecessary to remove any instrumentsupply or sense pressure. If the unitis a high switch, it will trip whenchanging the spring. If it is a lowswitch, it will not trip when changingthe spring. Precautions should betaken to avoid any unwantedreactions in the instrumentationsystem.3.1.2 To obtain access to the spring (Item2), rotate the lock ring (Item 4)clockwise to loosen it from the springcap (Item 1).3.1.3 Rotate the spring cap (Item 1)counterclockwise until it isdisengaged from the switch body(Item 10).3.1.4 Remove the spring from its cavity inthe switch body. If the parts tube(Item 3) is inside the spring, careshould be taken not to lose it.3.1.5 Follow the procedures in repair andassembly section (Steps 4.15 and4.16) of this manual re re-install thespring.B) PistonRemoval3.1.6 If the switch is panel mounted, it isnot necessary to remove it from thepanel. It will be necessary todisconnect any piping or tubing fromthe base that would prevent thebase from being removed. When theswitch is supported by the ½” NPTconnection on its base (Item 16),disconnect any piping or tubing fromthe switch body that would preventits removal from the switch base.CAUTION: Be sure that allinstrument or sense pressures arecompletely bled to zero beforedisconnecting any piping or tubing.3.1.7 Use the appropriate wrenches tohold and loosen the base from theswitch body. Unthread the basecompletely from the switch body.3.1.8 Use the small pliers and grip theraised ridge on top of the piston(Item 15) and pull it from the switchbase (Item 16).3.1.9 If the ¼” diameter piston (Item 19) isinstalled and must be removed fromthe large piston, use the properwrench to hold the ¼” diameterpiston and grip the large piston withthe pliers at the small diameterabove the groove for the .5” pistono-ring (Item 18). Rotate either onecounterclockwise to loosen andseparate the pistons.3.1.10 Remove the installed o-ring from thepiston.3.1.11 Procedures for re-installing thepiston o-rings are in the repair andassembly procedure of this manual.3.2 FULLDISASSEMBLYNOTE: Use the following instructions to completely disassemble the pilot for repair and cleaning. CAUTION: Be sure that all instrument or sense pressures are completely bled to zero before disconnecting any ping or tubing.3.2.1 Follow the procedures stated underpartial disassembly to remove thespring and pistons.3.2.2 Remove the spool (Item 14) from theswitch body. If it is necessary, usethe small pliers and grip the smallend of the spool. Removing thespool also removes the bottomsleeve (Item 13).3.2.3 To remove the top sleeve (Item 8),an o-ring pick (pointed prying tool)can prove useful. Just insert the pickinto one of the .041 holes in the topsleeve and pull the sleeve out. Notethat while using the pick, care shouldbe taken not to scratch the bore onthe top sleeve.3.2.4 The seals on the shaft and sleevesmay now be replaced as perinstructions given in the repair andassembly section of this manual.。

Connect the supplied RJ-11 phone line cable between the jack marked<Line> and your wall jack. Be sure this jack supports standard single lineanalog telephone operation.2. You may want to connect an auxiliary telephone to the innkeeperLTD <Phone> jack so you can dial out and set up calls, or use the<Auto-Answer> feature to answer incoming calls.Connecting to a Mixer (Mix Minus Caller)Note: A mix-minus signal is an audio signal that contains a mix of your local microphones plusany other audio, minus the Caller’s own voice. Sending the Caller’s audio back to the innkeeper LTD will cause an echo, or feedback.3. Connect the innkeeper LTD <Caller> output to any Line input on the mixer.4. Connect your microphone(s) to the mic inputs on your mixer.5. Connect the mixer’s Mix-Minus bus or Aux Send output (this may be labeledFX or Mon but any Aux bus will work) to the <Send> input on innkeeper 1rx.Set the innkeeper 1rx <Mic/Line> switch to the Line position.6. If your mixer doesn’t have a mix-minus bus: Whichever input channelyou have the <Caller> connected to, turn the corresponding Aux control tominimum. All Aux controls for other channels should be set for audio sentto the phone line. Each Aux Send bus is completely separate from all otheroutputs, so these Aux controls will not affect what is heard on the Mainoutputs or on any other Aux buses.Tip: Using an Aux Send bus that is Pre-Fader allows you to control the levels of eachchannel to the main output without affecting what is sent to the phone line.7. Connect your headphones to the mixer.8. Use Main Outputs to send audio to recording device or broadcastingequipment inputs.4innkeeper LTD™Digital HybridCompleting Setup9. Connect the supplied DC power supply to the back of the innkeeper 1rx and then to an AC power outlet.This device should be connected to an adequate surge protectivedevice at all times both for the power connector and for thetelephone line to avoid damage from lightning or electrical surges.10. Adjust the <Send> level controls so that you consistently light the green -20 dB and -9 dB and rarely light the red -3 dB peak Send LED. Theseflashes should occur only during loud speech bursts. If the red LED stayslit for extended periods you can assume that much of your speech is beingclipped or distorted. Set the <Caller> control for good recording level of thecaller audio at the output jack.5Getting ConnectedOperationAuxiliary TelephoneAn auxiliary telephone provides you with an easy way to dial out or set up your calls. innkeeper LTD will disconnect the auxiliary telephone when you press the <Call> button. If you need to take the call back on the aux telephone, simply pick up the telephone handset before the innkeeper LTD’s <Drop> button is pressed.To use an auxiliary phone equipped with a “Hold” feature to place or screen acall, first set up the call and place the call on hold. When you are ready to take the call on Innkeeper LTD, press the <Call> button on the innkeeper LTD andyour telephone will automatically release the hold.Your phone will operate as a normal telephone anytime you are in Drop mode.Leaving the hybrid connected between the wall jack and your telephone will not affect normal use of your phone.

Disconnect power fromthe hybrid and remove the cover of the innkeeper LTD to locate Jumper 1. The default position for this jumper is closed (covering both pins). Changing thejumper to the open position (either remove the jumper or cover just one pin) will provide 6 dB attenuation of the incoming audio signal.Auto-AnswerThe <Auto-Answer> feature will answer on the first ring. When <Auto- Answer> is enabled, you can still make calls manually using the <Call> button.When finished, you can either drop the call manually or allow the call toAuto-Disconnect. innkeeper LTD will look for a CPC disconnect signal from the phone company to determine when a call has disconnected.

Does the innkeeper LTD send a burst or beep downthe phone line at the beginning of each call like ourcurrent hybrid?No. Innkeeper LTD uses the actual transmit signal to evaluate the phone lineand tune its algorithm. As you begin to speak, innkeeper LTD is hard at workcanceling your voice from the Caller Output jack. Within milliseconds yourvoice is reduced into the noise floor.2. Can I use the innkeeper LTD on a VoIP line?Many VoIP lines have an analog telephone adapter you can connectyour telephone to. If you can use any standard analog telephone, theninnkeeper LTD should work great. If you have to use a specific telephone,you should consider our AutoHybrid IP2 VoIP hybrid or Innkeeper PBX digitalhybrid instead.3. The caller’s audio is too high and is always distorted eventhough I have the Caller level control turned down low. Whatelse can I do?The Receive LED meter will indicate the level of audio coming in from thetelephone line, just after it passes through the DSP. The Caller level controlwill only set how much of that audio will be sent to the output jack, and willhave no effect on the LED meter. If your incoming audio level is unusually hotand already peaking the –3 dB LED, there is a jumper on the circuit boardyou can change to attenuate the incoming audio. Please see page 6 formore information.4. I have my new innkeeper LTD connected to the phone jack inmy office. Why does it keep dropping the calls as soon as Itry to connect it?The telephone jack in your office is very likely for a multi-line phone system.The jack may look like a standard phone jack, but it is wired differently andmay carry voltage on different pins which could cause serious damage to yourhybrid.
