Safety Test
4-1.
Activate each
monitored device
and confirm the corresponding inputs’ red LEDs on MIM-62
turn on.
4-2.
Activate the operator and confirm that each monitored device stops and/or reverses as expected.
3-1. If
monitored devices
are not functioning, check for proper power connections, including polarity, if
necessary.
3-2. If, after the Learn button is pressed, one or both outputs are in fault (yellow LED on), check to see
which red LEDs are on. Confirm the device is connected to the assigned channel. If it is working,
confirm the output of the safety device is connected properly to the input connector.
3-3. If re-learning MIM-62 is necessary:
(a) Press the Learn button to clear settings
(b) Press the Learn button to learn new settings
3-4. If all
monitored devices
and MIM-62 are working (no red or yellow LEDs), and the operator is still
reporting a fault, confirm MIM-62 outputs are connected properly to the operator’s inputs. Also,
confirm the Output Interface is set correctly (pulsed or relay), as stated in the operator’s manual.

Troubleshooting
2-9. When all monitored safety device inputs are connected, turn on the power to the operator. MIM-
62 should display a brief light test followed by blinking of the Output A and Output B indicators.
The Learn Mode LED on the rear panel will also be lit. This indicates that MIM-62 is in Learn
Mode, and will display the present condition of each input channel’s sensor:
(a) On: solid
Open circuit (faulty wiring or nothing connected)
(b) Blinking
10K ohm terminated sensor (no fault indicated)
(c) Off: solid
Normally Closed sensor (no fault indicated)
(d) Fast Blink
Pulsed sensor (no fault indicated)
If there is a fault, correct any wiring or make selection changes before proceeding.
Note: The LEDs behave differently in Learn Mode versus Run Mode.
2-10. When all intended devices are connected and indicating no faults, momentarily press the Learn
button on the rear panel. The lights should flash, and then all the LEDs should go off, except the
green power LED. Test each entrapment device to confirm the associated red LED turns on when
the device is activated.
2-11. At this point, MIM-62 should be operational and may be mounted to its mounting location.
