MICRO SWITCH Merge PRIM 35,0 6'6 & 350AN-0005HONEYWELL Sensing and ControlFEATURESThe Merge PRIM is used to combine product from two conveyors to one. The product can be used both in an SDS network or using phone cable to connect to an adjacent prim.The PRIM is comprised of 3zones with each zone consisting of 1 detector and 1motor drive circuit and one zone used for additional inputs.HARDWARE RULES • Zones must not be able to completely contain 2 items or more at once.• Default transport from zone B to zone A and from zone C to zone A. Cannot be run in reverse.• Sensor B should be close to where the spur meets the main conveyor.• Sensor B must be further away from Photo A than Photo C is from Photo A. Failure to do so will result in collisions in the merge area when switching from spur to main.MERGE PRIM DIAGRAMMERGING ALGORYTHMThe merge uses the priority selection and zone status to determine whether the spur zone or the main zone is selected to merge. The merge rules are as follows:• Once started, a box will continue to merge until it has completely merged in to the merge area.• The zone with priority will halt the other zone until it is empty.• The zone without priority is allowed to merge until a box starts to enter the zone with priority.• When switching the merging zones, the new merge zone will start the merge immediately after the old merge zone has completed the merge. (note Photo B/C placement)CONNECTION TO ANOTHER PRIMUse the SDS or Phone Jack method. If the phone jack method is selected, the Extra Zone method must also be used to link the spur with the upstream PRIM. This means the spur’s upstream PRIM will require the use of Zone A to communicate with the merge module and will therefore have only 3 usable zone to operate conveyor.NOTE: The PRIM must be connected to either another PRIM via a phone jack or controlled by SDS in order for it to operate.MICRO SWITCH Merge PRIM 35,0 6'6 & 350AN-00052 Honeywell • Sensing and Control For application help: call 1-800-537-6945SDS METHODLink PRIMs together by copying input information from adjacent PRIMs to output data for this PRIM. Use the chart below as a guide to determine what sensor data (Item_Coming) and accumulate data (Ready_To_Send) should be copied.downstream Item_Coming = Merge.Input.0Merge.Output.3 = upstream main Item_Coming Merge.Output.4 = upstream spur Item_Coming Merge.Output.5 = downstream Accumulate upstream main Accumulate = Merge.Input.8upstream spur Accumulate = Merge.Input.9PHONE JACK METHODUse the Phone Jacks to attach adjacent PRIMs both upstream and downstream from the main line of the merge. The Spur requires the Extra Zone method to connect the adjacent e Zone D of the merge PRIM to interface with Zone A of the upstream PRIM on the spur side.• Merge Zone D photo to upstream Zone A Run • Merge Zone D run to upstream Zone A Photo • Upstream Zone A Dir and Flt togetherMERGE DIRECTIONThe direction of the last merge is also broadcast over SDS at input bit 13 (Merge.Input.13 - Zone D Active bit for the standard transport PRIM). The bit will be set when the merge occurs from the spur and will be clear when the main transports items through the spur. This data can be made immediately available by selecting it in the Input Mask attribute 50 of the merge PRIM (refer to PRIM Installation Instructions). Failure to have that bit selected only prevents the data from being broadcast immediately because that data will still be contained in every input data change of value transmission from the PRIM.PRIORITYPriority specifies which conveyor gets the right of way to merge when both are ready to send an item through the merge. The priority rules are:• Priority on spur main will prevent the spur from sending an item until the merge zone and main zone is empty.• Priority on the spur will prevent the main from sending an item until the spur zone is empty.• Priority will cause the non-priority side to stop transporting items when a new item is ready to transport on the priority side.• Default priority is on the main.• Priority can be selected using either the SDS network or via hardware.PRIORITY OVER SDSThe Merge output bit 17 (Merge.output.17) is the priority bit (this is the Zone D direction bit for the standard transport PRIM). By default, the bit is clear and priority is on the main conveyor.When set, the priority is on the spur. This bit can be toggled at any time and at the next available transition, the priority will be changed.PRIORITY WITHOUT SDSThe priority can also be changed without the use of SDS. The Zone D MOTOR_FLT input on the merge module will accept an open collector input to change the priority. When the input is active low for the programmed Zone Travel Time of about 1.5 sec (refer to Attribute 43 on the PRIM Installation Instructions), the priority will transition from the main to the spur. The priority will remain on the spur until both the input signal is removed and the spur is empty. If both conditions are met, the priority will then will switch back to main.An additional sensor may be placed upstream of the spur and wired into the Merge PRIMs Zone D MOTOR_FLT. This sensor will then detect when the spur is backed up and toggle the priority on the merge to transport those items away as quickly as possible. Once the spur has completed running out all of the backed up items, the priority will again switch back to main. Power the addition sensor with the Merge PRIMs power and ground.MICRO SWITCH Merge PRIM35,0 6'6 & 350 AN-0005 This Page intentionally left blank.For application help: call 1-800-537-6945Honeywell • Sensing and Control 3MICRO SWITCH Merge PRIM 35,0 6'6 & 350AN-0005Honeywell Inc.11 West Spring StreetPrinted with Soy Ink on 50% Recycled PaperHelping You Control Your WorldXXXXXX - 1 - EN IL50 GLO DMM Printed in USASALES AND SERVICEHoneywell’s MICRO SWITCH Division serves its customers through a worldwide network of sales offices and distributors.
