Operating Logic: The control can function in 2
modes:
Continuous Mode:The pressure switch terminals
are shorted. Upon application of output voltage,
the control activates output #1 after the preset off
time. It will continue to activate outputs sequen-
tially until input voltage is removed.
On Demand Mode:The pressure switch termi-
nals are connected to an isolated set of contacts of
a differential pressure switch. The control will acti-
vate the outputs sequentially whenever the pres-
sure switch contacts are closed. When the pressure
switch contacts open, the output sequencing stops.
Re-closing of the contacts will cause the control to
resume activating the outputs.
Program wire allows the user to select the maxi-
mum number of outputs to be activated.
