3.2.5 Alarms
The two-color
LED
will be
red
and the buzzer sounds when there is a level alarm status. It is necessary to connect a
level probe. (Optional -
Picture 2
).
3.2.6
LED color descriptions:
Green: pump running.
Blinking green fast: the pump is in delay time.
Blinking green slow: the pump is in lock-out time.
Red: the pump is running in calibration mode. (See section 3.1.1 for full description)
Blinking red: the system is in calibration mode. (See section 3.1.1 for full description)

MAINTENANCE & ACCESSORIES
4.1
MAINTENANCE
Routine maintenance on the
OPL BASIC
unit includes preventive maintenance on the squeeze tubes and keeping the
unit clean. Repairs to the unit involve modular component replacements. This minimizes spare parts inventory
requirements and speeds up the service process in the field.
4.1.1
Squeeze Tube Replacement
Replace squeeze tubes on regular maintenance intervals. A planned preventive maintenance schedule will insure
replacement before the tube fails. In the event the tube does rupture, clean all product from pump with a damp cloth.
Disconnect power before servicing the unit;
Remove the transparent lid from the pump;
Before removing the old tube, position roller assembly with rollers in a vertical position;
Remove the old tube starting from the left; lift the tube and rotate the roller assembly clockwise;
Before inserting the new tube, position roller assembly with rollers in horizontal position;
Insert new tube with flat sides facing towards the front; from the left side rotate the roller holder clockwise as you
press the pump tube in place;
Insert the transparent lid.
4.2
ACCESSORIES
It is possible to connect the system to a level float switch.

TROUBLESHOOTING
5.1
POWER LIGHT DOES NOT ILLUMINATE:
Check fuse on the circuit board.
Check input terminals on board for correct input voltage. Refer to the circuit board diagram (picture 2).
5.2
PUMP(S) OR SOLENOID WILL NOT ACTIVATE:
Check pump output terminals for loose screws and disconnected wires.
Check for proper voltage across motor windings (or solenoid contacts).
Check for obstruction in pump head (or solenoid).
5.3
TOO MUCH DETERGENT:
Check the voltage to the system.
5.4
TOO LITTLE DETERGENT:
Check the voltage to the system.
Check pump operation for proper speed (or check bowl feeder for obstructions).
5.5
PUMP RUNS TOO SLOWLY:
Check roller block for binding.
Check for proper input voltage (24 VDC applied to the pump motor terminals will result in the highest speeds).
Check for lubrication on squeeze tube.
