Operating Temperature: -40°C to 65°C
Storage Temperature: -40°C to 70°C
Operating Logic: The control can function
in 2 modes.
In Continuous Mode, the pressure switch
terminals are shorted. Upon application of
input voltage, the control activates output
#1 after the preset off time. It will continue
to activate outputs sequentially until input
voltage is removed.
In On Demand Mode, the pressure switch
terminals are connected to an isolated set
of contacts of a differential pressure switch.
The control will activate the outputs sequen
tially whenever the pressure switch contacts
are closed. When the pressure switch con
tacts open, the output sequencing stops.
Re-closing of the contacts will cause the
control to resume activating the outputs.

Caution:
1. Do not mount controls in high vibration areas with
out shock mounts.
2. Do not mount controls in areas of high dust or cor
rosive atmospheres without a protective enclosure.
3 Do not use a converter or inverter for the power
source.
4. Do not mount control in high transient voltage
areas without an isolation transformer.
5. Do not leave control box open.
6. Do not allow a local repair shop to repair the con
trols, as we employ some very sophisticated compo
nents that could be further damaged. For service, call
us directly: 800-323-2593.
