B&B ARMR
A Division of B&B Roadway and Security Solutions VP Revision B1
Symptom
Actions
Gate operator does
not respond when
commanded.
1.
Check CONN 9 for power when command is given.
2.
Check overload protector
3.
Check PLC output.
4.
Check that safeties are clear, and that IR Beams are aligned.
5.
Check PLC input.
6.
Check the +24VDC at CONN3 pins 8 and 10
Operator drives gate
too slowly.
1.
Check for any binding of the gate.
2.
Check the fluid level in the reservoir.
3.
Check the quality of the hydraulic fluid. Old fluid will
become sludgy and clogging of internal filter is possible.
MAX Runtime Error
1.
Check for any binding of the gate.
2.
Check the fluid level in the reservoir.
3.
Check the MAX RUN TIME setting in Parameters to insure
sufficient time is set for the gate size.
Date and time flash
on the PLC.
1.
Refer to step 4.11 of Installing and Programming the LXL
Operator for setting the date and time. (Optional, not
required to be set)
Gate does not stop
automatically when
encountering an
obstacle.
1.
Refer to step 4.15 of Installing and Programming the LXL
Operator for setting the Inherent Safety.
2.
Check for system pressure on Inherent Safety screen of the
PLC, if no reading is evident while gate is running suspect a
faulty pressure transducer.
3.
Check the functionality of the safety devices.
4.
Check safety device wiring, refer to sections 6 and/or 8
Fuses are blowing.
1.
Check for incorrect incoming power to the Printed Circuit
Board (PCB).
2.
Ensure all external devices are sending the correct voltage
to the PCB, and that there are no shorts.
PLC says Stop/Reset
activated.
1.
If using an external push button, ensure that the stop button
is a normally closed contact.
2.
If not using an external push button, ensure there is a
jumper wire between stop/reset and +24 stp/rst on CONN 3.
3.
Check the connection of the wire between the J1Pin 9
connector and I7 of the PLC.
4.
Verify shunt is present on JP1 between pins 1 and 2.
5.
Check F3.
Electric Motor turns
but gate does not
move.
1.
Check the fluid level in the reservoir.
2.
Check PLC outputs to see if Q1 turns on for an OPEN
and/or Q2 turns on for a CLOSE.
3.
Check for loose coupling between the electric motor and
pump assembly.
4.
Check for voltage between COM and HYD VAL 1 and 2 on
CONN 1 of PCB, and ensure wires connections are tight.
