Analogue outputMenu for basic settings (adapting the EDS 300 to the particular application) Two different types of programming enable Three different output models are available:EDS 300 with 1 switching output (1.2 A load capacity, no analogue output) EDS 300 with 2 switching outputs (1.2 A load capacity, no analogue output)EDS 300 with 1 switching output (1.2 A load capacity) and 1 analogue output (4...20 mA)2. MountingThe EDS 300 can be mounted directly onto a hydraulic block via the pressure connection (7/16 SAE 4 female).When used in critical applications (e.g. strong vibrations or knocks) the pressure connection must be mechanically decoupled via a Minimess hose. Mounting clamps are available as an accessory (see point 12.2 "Accessories - for mechanical connection").The electrical connection should be carried out by a qualified electrician according to the relevant regulations of the country concerned (VDE 0100 in Germany). The pressure switch housing must be earthed properly at the same time. When fitted into a hydraulic block it is sufficient if the block is earthed via the hydraulic system. In the case of Minimess hose-mounting, the housing must be earthed separately.Additional assembly notes which, from experience, reduce the effect of electromagnetic interference:Make line connections as short as possible. Use screened lines (e.g. LIYCY 4 x 0.5 mm 2)The cable screening must be fitted by qualified personnel subject to the ambient conditions and with the aim of suppressing interference.Direct proximity to connecting lines of user units or electrical or electronic units causing interference must be avoided as far as possible.3.Operating keys on the membrane keypad4-digitkeys for setting switchingdigital displayadditional functionspoints, switch-back points and e s y o f C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o mAfter switching on the supply voltage, the unit briefly displays EdS followed by the current pressure.In the basic settings the display can be altered. For example, the maximum value can be permanently displayed. This is the largest measured value which has been recorded since the unit was switched on or was last re-set. A switching point can likewise be permanently displayed or the display can be set to be dark. Depending on the setting, "TOP ", "S.P. 1","S.P. 2"or "OFF "key. This causesthe maximum value to be re-set.Notes:If the actual pressure exceeds the nominal pressure of the unit, it can no longer be displayed and the display begins to flash.If the actual pressure is below 1 % of the nominal range, then 0 is displayed.e s y of C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o m5.Output function5.1 Switching outputsThe EDS 300 has 1 or 2 switching outputs. The following settings can be made under the basic setting:5.1.1Switching point setting (SP)One switching point and one hysteresis can be set for each switching output. The respective output switches when the pre-set switching point is reached and switches back when the pressure falls below the switch-back point. The switch-back point is determined by the pre-set hysteresis (switch-back point = switching point minus hysteresis).Abbreviations:"S.P.1", "S.P.2" =switching point 1 or 2"h.Y.1", "h.Y.2" = hysteresis 1 or 25.1.2 Window function setting (WIN)The window function enables a range to be monitored. For each switching output, in each case an upper and a lower switching value can be input which determine the range.The respective output switches when the pressure enters this range. Upon leaving the range, i.e. when the switch-back value has been reached, the output switches back. The lower switch-back value is just below the lower switching value (lower switching value minus three times the increment, see point 5.4). The upper switch-back value is just above the upper switching value (upper switching value plus three times the increment, see point 5.4).The area between switching and switch-back value forms a safety zone which prevents unwanted switching operations from occurring (e.g. triggered by pulsations from a pump).Example for switching output 1 (normally open function):Abbreviations:"hi.1", "hi.2"= Hi gh level 1 or 2 = upper switching value 1 or 2"Lo.1", "Lo.2"= Lo w level 1 or 2= lower switching value 1 or 2Note:The window function only operates correctly (switching on and off), when all switchingvalues (including the safety zone) are greater than 0 bar and lower than the nominal pressure range.5.2 Analogue outputhi.1 plus 3xincrementLo.1 minus 3xincrementPON OffSwitch-back valuet Switching valueSwitch-back value Switching value hi.1e s y of C M A /F l o d y n e /H y d r a d y n e ▪ M o t i o n C o n t r o l ▪ H y d r a u l i c ▪ P n e u m a t i c ▪ E l e c t r i c a l ▪ M e c h a n i c a l ▪ (800) 426-5480 ▪ w w w .c m a f h .c o mPress "mode" key"S.P.1" or "hi.1" is displayedKeep pressing the "mode" key until the required parameter is displayed (depending on the basic setting: "S.P.1", "h.Y.1", "S.P.2", "h.Y.2", "hi.1", "Lo.1", "hi.2" or "Lo.2").keys to alter the setting.keys.If no keys are pressed for 3 seconds, the display changes back and the settings are saved.pressure displaypress mode key displayuntil the required parameter isreached.Notes:If "LOC" appears in the display when trying to alter the settings, programming is disabled.Corrective action: set programming enable to "ON"(see point 7 "Programming enable")key is held down during alteration, the value automatically advances.

The operating programming enable can be set or removed during operation. It provides protection from unintentional alteration.

相应的输出会在达到预设开关点时切换并在压力下降到回复点以下时切换回复。

预设延滞决定开关回复点。

（开关回复点=开关点-延滞）缩记： “S.P.1”, “S.P.2” = 开关点1或2“H.Y.1”, “H.Y.２”= 延滞1或25.1.2 视窗功能设置(WIN)视窗功能可监测一定范围内的情况。

对于每路开关量输出而言，设置一个高位开关值和一个低位开关值，由该两个值确定监测范围。

当压力上升进入到低位开关值，则相应输出发生切换。

也支持外部扩展干簧管接口，实现不开盖调整。

此时支持两个按键，分别为“S”、“Z”。

针对这两种应用，本产品支持“双按键”和“三按键”两种操作模式。

“三按键”操作模式：操作更快捷，适用于LCD上具备3个按键的产品。

➢Z键用于进入提示数据设置界面和移位；➢S键用于进入数据设置界面、增加数字和数据保存；➢M键用于数据保存。

注：在三按键模式下，任何时候都可以按下“M“键，保存当前的设置数据。

“双按键”操作模式：这种操作模式通常用于外部只有2个非接触按键的情况。

➢Z键用于进入提示数据设置界面和移位；➢S键用于进入数据设置界面、增加数字和数据保存。

注：在双按键模式下，输入数据时，必须等左下角的下箭头闪烁时，才能通过按下“Z”键保存设置数据。
