Overview EZ-SCREEN LPInstruction ManualInstallation and AlignmentExternal Device Monitoring HookupIf not connected previously, it is again strongly recommendedthat one normally closed, forced-guided monitoring contactof each FSD and MPCE be wired as shown in the monitoringcircuit (see Figures 3-24 and 3-26). Pins 2 and 3 of the receiverconnector provide connection for the external device monitoringinput. External device monitoring (EDM) must be wired inone of three configurations described below and this wiringconfiguration must agree with the receiver’s EDM DIP switchsettings (see Section 4.2).One-Channel Monitoring: This is a series connection of closedmonitor contacts that are forced-guided (mechanically linked)from each device controlled by the EZ-SCREEN LP. The monitorcontacts must be closed before the EZ-SCREEN LP can bereset and the OSSDs can turn ON. After a reset is executedand the safety outputs (OSSDs) turn ON, the status of themonitor contacts are no longer monitored and may change state.However, the monitor contacts must be closed within250 milliseconds of the OSSD outputs going from ON to OFF.See Figure 3-19.Refer to Figure 3-26 for 1-channel EDM hookup. Connect themonitor contacts between +24V dc and EDM1 (pin 3). LeaveEDM2 (pin 2) open (no connection), unless using the AuxiliaryOutput feature (Section 3.5.5). Set the configuration DIP switchto the 1-channel EDM position, per Section 4.2.Two-Channel Monitoring: This is an independent connectionof closed monitor contacts that are forced-guided (mechanicallylinked) from each device controlled by the EZ-SCREEN LP. Themonitor contacts must be closed before the EZ-SCREEN LP canbe reset and the OSSDs can turn ON. Regardless of the state ofthe OSSDs, the monitor contacts may change state (either bothopen, or both closed). If the monitor contacts remain in oppositestates for more than 250 milliseconds, a lockout will occur.Refer to Figures 3-24 or 3-26 for 2-channel EDM hookup.Connect the monitor contacts as shown between +24V dc andEDM1 (pin 3) and between +24V dc and EDM2 (pin 2). Set theconfiguration DIP switch to the 2-channel EDM position, perSection 4.2.No Monitoring: Use this configuration initially, in order toperform the initial checkout; see Section 3.6. If the applicationdoes not require the EDM function, it is the user’s responsibilityto ensure that this configuration does not create a hazardoussituation.Refer to Figure 3-25 for “no monitoring” hookup. To configurethe EZ-SCREEN LP for no monitoring, connect or jumper EDM1(pin 3) to EDM2 (pin 2) using the supplied wire-nut. Set theconfiguration DIP switch to the 2-channel EDM position, perSection 4.2.An alternate method to configure no monitoring is to set theconfiguration DIP switch to the 1-channel EDM position, perSection 4.2, and connect EDM1 (pin 3) to +24V dc. This methodallows the use of the auxiliary output (see Section 3.5.5) inapplications that do not require the EDM function.3.5.4 Remote Test InputAn emitter connection is provided (Test) for the connection of anexternal remote test switch (typically a normally open contactheld closed). Opening this switch “turns OFF” the emitter,simulating an interruption of the light beams; all OSSD outputswill turn OFF. This input is used in conjunction with the emitterTest/Reset DIP switch. See Sections 2.7.2, 4.2, and Figure 3-23.3.5.5 Auxiliary (OSSD Follow/Fault) OutputEZ-SCREEN LP receivers have an auxiliary status output thatprovides a PNP current-sourcing output (250 mA max.) thatmirrors the state of the OSSDs or indicates a lockout (ON =Fault). The output is on pin 2 (orange/black wire) when theEDM configuration DIP switch is set to the 1-channel monitoringposition, per Section 4.2. See the 1-channel EDM circuit onFigure 3-26 for hookup information.To use the auxiliary output in an application configured for nomonitoring, set the configuration DIP switch to the 1-channelmonitoring position, per Section 4.2, and connect EDM1 (pin 3)to +24V dc (see Section 3.5.3).The emitter also has a Fault output that can be enabled toindicate the emitter lockout status (see Section 4.2 Fault).3.6 Preparing for System OperationAfter the initial trip test has been accomplished, and the OSSDsafety outputs and EDM connections have been made to themachine to be controlled, the EZ-SCREEN LP is ready for testingin combination with the guarded machine.The operation of the EZ-SCREEN LP with the guarded machinemust be verified before the combined EZ-SCREEN LP andmachine may be put into service. To do this, a Qualified Personmust perform the Commissioning Checkout Proceduredescribed in Section 6.2.3.7 Sensor “Swapability” and Emitter HookupFigure 3-22 illustrates a hookup option that provides sensorinterchangeability (or “swapability”) – the ability to install eithersensor at either QD connection. This allows the emitter andreceiver positions to be easily swapped, similar to a popularfeature of Banner MACHINE-GUARD ™ , MINI-SCREEN ®andMICRO-SCREEN ®safety light screens, providing advantagesduring installation, wiring, and troubleshooting.To use this option, connect all emitter wires in parallel (color-for-color) to the receiver cable via individual wires or the CSB..splitter cordset.Buy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com
