Banner EZ-SCREEN LPM Series - Emitter and Receiver Resets

12.3 Emitter and Receiver Resets
WARNING:
• Lockouts and power failures indicate a problem
•
Attempts to continue to operate machinery by bypassing the Banner device or other safeguards
is dangerous and could result in serious injury or death.
• A Qualified Person
17
must immediately investigate the problem.
WARNING:
• Shut down the machinery before servicing
•
Servicing the Banner device or system while the hazardous machinery is operational could result
in serious injury or death.
• The machinery to which the Banner device or system is connected must not be operating at any
time during major service or maintenance. This might require lockout/tagout procedures (refer to
OSHA1910.147, ANSI Z244-1, ISO 14118 or the applicable standard for controlling hazardous
energy).
The EZ-SCREEN LPM receiver and emitter each have a Reset input that provides for a manual reset input signal.
The receiver requires a manual reset to clear a Latch condition and resume operation following a stop command. Internal
Lockout conditions also require a manual reset to return either the emitter or the receiver to Run mode after the failure has
been corrected. Emitter resets are needed only in the unlikely event that a Lockout occurs.
Receiver manual resets are required in the following situations:
•
Trip Output operation – only after a Lockout (see
Lockout Conditions (p. 76) for causes).
• Latch Output operation – at power-up, after each Latch condition occurs, or after a Lockout.
Reset Routine
To reset the emitter and/or receiver:
1. Close the reset switch for 0.25 to 2 seconds.
2. Open the reset switch.
An alternative method to reset either component is to power the sensor down, then power it up.
If reset switch model MGA-KSO-1 (see
Accessories (p. 82) ) is used:
1. Turn the key 1/4 turn clockwise to close.
2. Turn the key counterclockwise, back to its original position, to open.
Note: Closing the reset switch too long will cause the sensor to ignore the reset request; the switch must
be closed from 0.25 seconds to 2 seconds, but no longer.
Note: If the receiver is set for latch output, a manual reset using a remote switch, as described in , is
required to resume full operation.
