Power/Status LED

Status/Faults

Solid red

An undeclared fault has occurred.
Cycle power to clear the fault and return the GLT to an operational state.

Flashing red 1 time

The GLT is in configuration mode.
When the Logic Switch is set to 0 or 9 and the power is cycled, the PWR/Fault LED 
will blink at a 1X rate. The GLT is in configuration mode. Rotate the switches to the 
desired positions and cycle power.

Green with Flashing red 2 times

The configuration does not agree with the EPROM.
One or more of the rotary switches have changed during operation. The GLT will 
continue to operate, and the switch(es) can be returned to their original position. If 
the outputs are ON, turn the outputs OFF and press reset to clear the fault.

Green with Flashing red 3 times

The connection to terminal B2 has changed. 
The GLT will continue to operate, and the connection can return to its original status. 
If the outputs are ON, turn the outputs OFF and press reset to clear the fault.

Green with Flashing red 4 times

The safety inputs were closed before the delay time expired.
Open the safety input for the full time cycle. Or connect B2 to 24V and reconfigure 
the GLT for retriggerable inputs. 

Green with Flashing red 5 times

The gate appears open when it supposed to be closed and locked.
The IN1 indicator is OFF - input signals are corrupt.
The 51/L61 indicator is ON - gate should be locked.
Possible fault conditions:

Gate is open

Open circuit on S12

Open circuit on S22

Short from S12 to S22

Short from S12 or S22 to +24V DC

Short from S12 or S22 to 24V Common.

Check the voltage at terminals S12 and S22. Both should have 24V DC. 
Correct the fault. Press Reset to clear the flashing red indication. Press Reset again to 
turn the outputs ON. Cycle both input signals (or cycle power) to return the GLT to an 
operational state.

Flashing red 2 times

Upon power up, one or more of the rotary switch settings do not agree the value 
stored in the EEPROM.
Return the switches to their originally configured settings and cycle power or 
reconfigure the GLT.

Flashing red 5 times

IN1 is flashing 12 times.

Short circuit fault on terminal L11 to 24V.

Short circuit fault on terminal L11 to ground.

With OSSD Guardlocking or E-stop function…

Short circuit fault on terminal 51 to ground.

Correct the fault and cycle power to the GLT.

Flashing red 6 times

IN1 is flashing 7 times

Short circuit fault on terminal 14 to ground or

Short circuit fault on terminal 24 to 24V with pulse testing

IN1 is flashing 8 times

Short circuit fault on terminal 24 to ground or 

Short circuit fault on terminal 24 to 24V with pulse testing or 

Short circuit fault from terminal 14 to terminal 24 with pulse testing.

Correct the fault and cycle power to the GLT.

Flashing red 9 times

IN1 is flashing 9 times

Short circuit from terminal 51 to L61

Open circuit on terminal 51 or L61

IN1 is flashing 10 times

Short circuit fault on terminal 51 or L61 to ground or 

Short circuit fault on terminal 51 or L61 to 24V.

Correct the fault and cycle the power to the GLT.

Flashing red 10 times

IN1 is flashing 33 times

The supply voltage exceeded 26.4V DC - Overvoltage

Correct the power supply and cycle the power.
