Dual Action Pump
Relay
When two or more controllers are connected to a master valve or
pump circuit there are both potential and inevitable problems, especially during
maintenance and repair of the controllers. Adding a pump relay to
each controller solves some problems but ISOLATOR
offers double protection by locking out all controllers except one, and for
about the same price. Below are three common problems of interconnected
controllers.
 |
FEEDBACK:
When the first
controller begins a cycle, it sends power to the pump or master valve which
is also connected to the other controllers. Some controllers exhibit
strange behavior, like starting a cycle, when external power is applied to
their Pump/Master Valve terminal. |
|
POLARITY:
When a controller is removed for repair, the transformer wires can easily be
reversed when it is reinstalled. It's common terminal will be a 24
volt difference from the other common wires. |
|
PHASING:
Phasing problems occur when controllers are on different "legs" of
a 240 volt utility service. The 120 volt supply to the controllers is
out of phase. ISOLATOR provides the only method of interconnecting
these controllers to operate a pump or master valve. |
If you have these problems you need
ISOLATOR.
Add to the mix several brands of controllers, both mechanical and digital, old
and new, then you really need ISOLATOR!
