A Word About Triacs
A triac is an electronic switch and can “latch on” when it becomes overheated from a laboring motor (tight seal pack). It
may operate properly when it cools down. A continuously running motor could be caused by an overheated triac. Checking
the seal pack and voltage draw and allowing the triac to cool down could give you favorable result and prevent the need to
change the board. Otherwise, when it is sent to Returned Goods it could test good and be returned.
You Clear an Error Code and it Starts Into Reconditioning Cycle
It was either in reconditioning cycle or has kept track of time since the error code occurred and it’s trying to finish
the reconditioning cycle. Reset and reprogram the board.
The Board Repeatedly Defaults, Resets or Gains Time
Look at the power supply or source. Most of these issues are caused by the power source, so-called “dirty power” having
noise interference or incorrect voltage. This could be erratic fluctuations caused by other heavy power draws, poor wiring,
low voltage wiring running along high voltage, having active electrical storms that causes “corruption” of the EEPROM.
Consider the use of a surge protector or an uninterruptible power supply after you see this repeatedly.
If you suspect the power source is causing problems, take a voltage reading at the outlet, at the power connection on the
board, and on the motor leads while the motor is running. We are looking for a consistent range of 108-132 volts at the
receptacle and 22-28 volts on the board. Also, the wall transformer is only used to step down the voltage; it is not used for
protection or filtering the power source.
Test Mode
In this mode the control can be put through a performance test to verify the operation of the board components. Moving dip
#1 from service to test mode enters the test mode; the motor output should turn off (if it was on) upon entering test mode.
When entering test mode all program settings and statistical data should be stored in EEPROM. The test sequence is to
follow the description as found in the table below. Upon exiting test mode, if a device connection is different (flow meter
connected or disconnected) or a DIP switch setting is changed from the condition that was present when entering test mode,
the control should behave as if the change was made while out of test mode. For example, if a flow meter was added and not
removed while in test mode, the control shall load the flow meter defaults when exiting test mode.
