Operating Logic: The DNC-T2110-A10/
B10 are ten output sequencer, cycle tim
ers with adjustable ON-TIME, OFF-TIME

-

and DELAY times. When voltage is applied
to L1 and L2 and the pressure switch is

-

closed, the OFF-TIME is started, At the
end of the preset OFF-TIME the control

-

will cycle through the outputs until the

-

pressure switch opens. The ENABLE/
DISABLE switch on the control can enable
the OFF-DELAY. When the pressure switch

-

opens and the OFF-DELAY is enabled, then
the OFF-DELAY time is started and the
OFF-TIME, ON-TIME cycles will continue
until the end of the OFF DELAY time. If the
OFF-DELAY times out during the ON-TIME,
the control will allow the ON-TIME to time
out. Upon closing of the pressure switch
the control will commence the OFF-TIME,
ON-TIME sequence on the next output and
the OFF-DELAY time will reset. If the pres

­sure switch is closed during the OFF-DELAY
time, the control will reset the OFF-DELAY.

-

The ENABLE/DISABLE switch on the con

­trol can disable the OFF-DELAY. When the
OFF-DELAY is disabled and the pressure
switch opens, during the ON-TIME, the
control will allow the ON-TIME to time out.
Upon closing of the pressure switch the
control will commence the OFF-TIME, ON­TIME sequence on the next output.

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.
