Q: LT-300: The pump turns on for only a second then goes off?
A: Check the run time of the pump.
Q: LT-300: The pump runs continuously.
A: Make sure jumper JP6 is selected for "normally open" operation.
Q: Probe-type system feeding continuously.
A: Wires to probe are off.
Q: Probe-type system won’t feed at all.
A: The probe wires or the probe itself may be shorted. Try removing the probe wires from the circuit board (temporarily) to determine if the unit will then feed.
Q: The pump stops after only a few seconds (or almost immediately after starting) and the alarm is sounding.
A: The alarm delay is set too short. Probe systems use an adjustable alarm delay to warn of problem conditions, and to also shut the pump off when the delay time has expired.
Q: The system has been programmed but the pumps will not run when they get a signal.
A: Check formula volume settings and flow rates. For testing purposes, try programming a much smaller volume to verify if the pump will run (the volume called for may be exceeding the maximum pump run time).
Q: LLA-400 The alarm sounds continuously and won't turn off.
A: May simply need to re-calibrate the pressure sensor. Otherwise, check all of the air line connections, and make sure the pressure sensor wires have not come loose from the circuit board..
Q: SA-12 The light will not turn off, it stays on all the time.
A: First make sure the device that the SA-12 is connected to is not experiencing any problems. Then check all wiring connections between the SA-12 and the device to make sure they are correct.
Q: Why did my dispenser lose memory?
A: Excessive levels of electrical noise and/or power surges can cause problems with dispenser memory. In these situations, using a good quality surge protector/noise filter should prevent any loss of memory.
Q: The pump will not stay primed.
A: Check the condition of the squeeze tube and roller block. Make sure there are no air leaks where the flow tubing connects to the pump.
Q: Why do I keep blowing fuses in my dispenser?
A: Check for a direct short. On-board fuses generally will blow if a motor (or output circuit) is bad. In-line fuses to the transformer can blow from the same conditions, but most likely if the transformer is shorted.
Q: There is water going back in to the chemical container on my ILCS or laundry dispenser.
A: When a flush manifold is used, the checkvalves on the individual chemical ports prevent water from pushing back through the pump. Inspect the checkvalves and replace as needed.
