26. SHADOW LOOP IS INEFFECTIVE
1. The gate is not at either the open or close limit.
2. Bad loop sensor or loop detector.
3. Bad connection between the loop sensor, loop detector and the Control Board.
4. Only one gate is on the limit (Master/Slave systems only).
27. MAGLOCK DOES NOT WORK
1. Bad connection between Maglock, its power supply and the Control Board.
2. Bad Control Board( relay on the Control Board does not close).
3. Bad Maglock or Maglock power supply.
4. Large gap between gates.
28. MASTER/SLAVE SYSTEM
Units work as stand-alone:
1. Miswired or disconnected Master/Slave interconnect cable.
2. Improper Master/Slave switch S1 setting.
3. Bad control board.
Units are not synchronized:
Improper switch S1 Master/Slave settings.
One gate braking to stop causes a fault in the other (moving) gate:
1. Both units are wired to the same circuit breaker.
2. Undersized power wires.
B. FAULT LIST
The following conditions can cause a fault in the SW 2000-B1 gate operator system:
1. Interrupt Bar activation.
2. Average motor overcurrent (overload) caused by excessive motor current.
3. Instantaneous motor overcurrent (left/right reverse sense) due to an impact on the gate.
4. Maximum motor run time exceeding 75 seconds.
5. Inoperative motor caused by an open motor winding, broken or unconnnected input motor
wires, or thermal overload.
6. Limit switch staying closed when gate is supposed to move, caused by a broken V-
belt, defective limit switch, or defective cams.
Faults 1, 2 and 3 may be cleared at any time by the following, if Fault Re-Try is ON:
• All open commands (Open, Radio, Exit, Fire)
• Manual commands (Open, Close, Stop)
Faults 1, 2 and 3 may be cleared at any time by the following, if Fault Re-Try is OFF:
• Fire command
• Manual commands (Open, Close, Stop)
• All other commands must wait 60 seconds to clear these faults.
Faults 4, 5 and 6 may be cleared at any time by the following:
• All open commands (Open, Radio, Exit, Fire)
• Manual commands (Open, Close, Stop)
