Instruction Manual
4.2 Reset Procedures
4.2.1 Receiver Resets
The EZ-SCREEN Grid receiver has a RESET input, terminal 5, that allows the
System to be manually reset. To reset the receiver, close the Reset switch for 1/4
to 2 seconds, then open the Reset switch. (If Reset switch model MGA-KS0-1,
listed in Section 2, is used, close the switch by turning the key 1/4 turn
clockwise; open it by turning the key counterclockwise, back to its original
position.)
NOTE: Closing the Reset switch too long will cause the system to ignore the reset
request; the switch must be closed at least 1/4 second, but no longer than
2 seconds.
Receiver manual resets are needed in the following situations:
• When operating in Trip Output mode, manual resets are required only after a
system lockout (see Section 5 for causes).
• When the System is in Latch Output mode, a manual reset is required at
power-up, after each latch condition occurs, and after a system lockout.
4.2.2 Emitter Resets
In the rare occurrence that an emitter requires a reset, power the sensor down,
then power it up. Emitter resets are needed only if a lockout occurs.
4.3 Status Indicators
A variety of status indicators on both the emitter and the receiver are clearly
visible on each sensor’s front panel (see Figure 4-1).
Emitter: A single bi-color red/green Status indicator shows whether power is
applied, and whether the emitter is in Run mode, Test mode, or Lockout mode. A
7-segment diagnostic display indicates a specific error code when the emitter is
in Lockout mode. The 7-segment display also momentarily indicates the scan
code setting at power-up or when changed.
