INPUTS
•
Check if AC POWER ON/OFF SWITCH (on MAX toroid box) is ON.
•
Check if power cable is plugged into back of MC-200 “Power In” input.
•
Check wiring between Matrix 1 RS485 (+,-, gnd) and MC-200 RS485 (+,-, gnd) terminals. Connect [(+) to
(+)], [(-) to (-)] and [GND to GND].
•
Check if limit switch box is plugged into MC-200 “LIMIT SWITCH” input on back.
•
Check if gate is binding against catch post or bracket in opened or closed position.
•
Check if gate moves manually with low resistance throughout its full range of motion.
•
Check if hinges are operational and well greased.
•
Check if operator is positioned properly relative to the gate hinge, (see ).
•
Gate may be too heavy for operator (check manual for maximum gate weight for your model operator).
•
An entrapment event has occurred, check an entrapment sensor was triggered (see if ERD, EDGE 1, EDGE 2, or
PHOTOCELL LED is on).
•
An ERD event may have occurred. Check for gate obstruction.
•
ERD sensitivity is too high for application. Re-adjust ERD setting on MC-200, (see ).
•
Sensor on EDGE 1 input (photocell or edge) may have detected an obstruction while closing the gate.
•
Photocell on EDGE 1 input is misaligned with reflector.
•
Sensor on EDGE 1 input (photocell or edge) may not be wired properly, (see ).
•
Sensor is NOT a N.C. monitored sensor that is UL325 2016 compliant.
•
Sensor is damaged or malfunctioning.
•
Jumper between EDGE 2 and GND is missing or broken (jumper is required if a sensor is not present).
•
Sensor on EDGE 2 input (photocell or edge) may have detected an obstruction while opening or closing the gate.
•
Photocell on EDGE 2 input is misaligned with reflector.
•
Sensor is NOT a N.C. monitored sensor that is UL325 2016 compliant.
•
Sensor on EDGE 2 input (photocell or edge) may not be wired properly, (see ).
•
Sensor on EDGE 2 is damaged or malfunctioning.
•
Sensor is NOT a N.C. monitored sensor that is UL325 2016 compliant.
•
Jumper between PHOTOCELL and GND is missing or broken (jumper is required if a sensor is not present).
•
Sensor on PHOTOCELL input (photocell or edge) may have detected an obstruction while opening or closing gate.
•
Photocell on PHOTOCELL input is misaligned with reflector.
•
Sensor on PHOTOCELL input (photocell or edge) may not be wired properly, (see ).
•
Sensor is NOT a N.C. monitored sensor that is UL325 2016 compliant.
•
Sensor on PHOTOCELL is damaged or malfunctioning
•
MOST sensitive setting for ERD entrapment detection. Select a less sensitive setting (recommend level 10 thru 16)
