FLAT MOTOR DRIVEN ROLLER CONVEYOR STRAIGHT AND CURVE TECH HANDBOOKZERO-PRESSURE CONTROLS: POWER DISTRIBUTION WIRING (Continued)E-STOP (WHEN REQUIRED)POWER SUPPLYE-STOP LOAD BREAKCONNECTORQD1CB2CB3QD2PATCH CABLESPatch cables are used to bring power from a 24VDC power supply to flat motor zones that cannot be reachedwith standard trunk line wiring. Adjacent conveyors may also be powered by using patch cables. Care must betaken not to exceed power supply capacity as well as the current limit per power supply circuit, depending uponpower supply size.TERMINATING CAPSTerminating caps are installed at each end of the power distribution trunk line to prevent accidental shock orshort circuit.NOTE: Power supply cycling is not recommended. A load break contactor should be installed after the powersupply in order to break power to the power distribution system as required.<strong>FMDR</strong> TECHNICAL HANDBOOK 2014.130
FLAT MOTOR DRIVEN ROLLER CONVEYOR STRAIGHT AND CURVE TECH HANDBOOKZERO-PRESSURE CONTROLS: ENTRY ZONEENTRY ZONEThe zone where the first product enters the conveyor is referred to as an entry zone. This entry zone must beconfigured with a wake-up signal to activate the rollers in anticipation of a product. This wake-up signal can beprovided with an upstream sensor or a 24VDC signal from an upstream device. The entry zone will also havedifferent DIP switch settings and communication wiring than other flat motor zone types.Configure an entry zone as follows:DIP SWITCHESSwitch 1: Set for correct motor directionSwitch 2: OFFSwitch 3: ONSwitch 4: OFFNote: An entry zone cannot be configured to be an entry zone while controlling a slave zone at the sametime.COMMUNICATION WIRINGDownstream communication wiring in an entry zone is configured with a 6-wire modular phone cable as shownon page 25. Upstream communication must be configured through the I/O connections. Do not connect a 6-wiremodular phone cable to the upstream communication port. Connecting a cable to the upstream port may causeundesirable results. Entry zones can be set up as manually loaded or automatically loaded. Manually loadedentry zones must have a sensor (photo-eye) located on the upstream equipment to wake-up the conveyor whenthe first product arrives. Automatically loaded entry zones are configured to handshake with upstreamequipment by providing a ready signal and accepting a sending signal. Each configuration must be wired asfollows:MANUALLY LOADED ENTRY ZONEA manually loaded entry zone must have a sensor located about 6 inches upstream from the entry zone.Typically, this sensor is a photo-eye, referred to as a wake-up photo-eye. If the entry zone is the first zone inthe system and there is no equipment upstream, place the wake-up photo-eye near the beginning of thezone. A manually loaded entry zone will have two photo-eye sensors wired to the same ZPA module. Thezone photo-eye, located at the downstream edge of the zone, will be wired the same as a typical sensor,shown on page 24. The wake-up photo-eye will have the (+24VDC) and (-) wires connected to the sensorterminals. The black signal wire from the wake-up photo-eye must be connected to Smart Input 2, as shownbelow.WAKE-UP PHOTO-EYEZONE PHOTO-EYEPOWER WIRE<strong>FMDR</strong> TECHNICAL HANDBOOK 2014.131
