ADJ 1100 Smart Pump & 2500ES Electronic Timer Trouble Shooting Guide
Trouble Condition: The pump has stopped pumping product.
Possible reasons:
1. The pump head air logic valve is not working.
2. There is not enough air pressure being applied to lift product.
3. The pump has a blockage somewhere in the pump head.
Trouble Shooting Procedure:
1. If the air from the pump air exhaust tubing is coming out in a steady stream or is not pulsing at all, remove the pump from the well. Remove the pump head pulse-rate adjustment port plug. Insert a small flat head screwdriver into the air logic valve and increase the pulse-rate to maximum. If the air exhaust remains a steady stream of air, then the air logic valve must be changed and the air supply should be checked for water moisture. If the pulse rate of the pump is OK (pulse-rate range= 10-80 pulses per minute), go to step 2.
2. Do a quick review of what the optimum air pressure should be for the present depth of your skimmer. If the air pressure is OK, go to step 3.
AIR PRESSURE = 35 + Total Vertical Lift
2.85
Minimum operating pressure is 35 PSI
Maximum operating pressure is 125 PSI
Trouble Condition: The Timer product tank full light does not come on when the timer power switch is turned on.
Possible reasons:
1. Power to the timer is not on or wired correctly.
2. Battery is dead.
3. DC or AC fuse has been blown.
Trouble Shooting Procedure:
1. Check out the power source and all wiring.
2. Replace the battery and install a solar panel for longer operation.
3. If the DC or AC fuses are blown, check out the wiring to the battery or to your AC source. The DC fuse is accessible from the bottom outside of the timer (use a 2amp fuse). The AC fuse is inside the timer (on the back of the PC board), use a 1/10 amp fuse.
Trouble Condition: The Timer product tank full light stays on with an empty product tank.
Possible reasons:
1. DC power to the timer is below 12 volts.
2. The tank sensor wire connections are loose or incorrect.
Trouble Shooting Procedure:
1. With the timer's power switch in the on position, mm the pumping time in minutes knob to the Cont. position. Check the voltage at the battery for 12 volts. If the voltage is low and a solar panel is connected to the timer, check the position of the solar panel. The solar panel should be pointed due South at a 45 degree angle upward towards the sun. If the power is OK go to step 2.
2. Check out the wire connections in the timer junction box to the holding tank sensor cable. If the junction box connections look OK, check out the holding tank sensor cable connection at the holding tank. If the red still stays on, you may need to replace the tank sensor or the timer or both.
Trouble Condition: The Timer's digital clock is not accumulating time when the skimmer is running.
Possible reasons:
1. The operating pressure to the timer is below 35 psi.
2. The wiring from the pressure switch to the digital timer is faulty.
3. The pressure switch inside the timer is faulty.
Trouble Shooting Procedure:
1. The digital timer receives a signal from a pressure switch inside the timer when the timer solenoid is activated and the operating pressure is above 35psi. Check out the operating pressure being delivered to the timer. Watch out for bad pressure gauges at the air source. If the operating pressure is OK, go to step 2.
2. Check the wire connector plunged into the back of the digital timer for being lose or lose wires coming out of the connector. If everything looks OK, go to step 3.
3. The pressure switch inside the timer closes an electrical contact inside the switch when the switch is exposed to 35psi. To check out the pressure switch, remove the front control panel, turn on the power switch on the front control panel, and turn the pumping time in minutes knob to the Cont. position. Check the electrical contacts at the pressure switch. The contacts should be shorted. You may need to replace the pressure switch assembly.
Trouble Condition: The timer digital elapsed time is a lot more than was selected.
Possible reasons:
1. Timer solenoid valve inside timer is not shutting off properly.
Trouble Shooting Procedure:
1. The solenoid is a spring loaded normally closed valve. It is possible that some debris has found its way into the valve which could cause the valve not to close completely. To resolve this problem you can return the timer to the factory or disassemble and clean the valve yourselves.
Replacing The Skimmer Diaphragm
1. Loosen all bolts until pump bottom can be detached. Do not separate pump head, valve housing, or diaphragm from the six bolts at this time.
2. Lay pump on it's side on the table and remove the diaphragm from all six bolts.
3. Place new diaphragm onto the six bolts and reattach upper pump parts with the pump bottom.
