SERIES DCP100A/200A PRESSURE MODULES
Specifications – Installation & Operating Instructions
2.0 Demand Mode using a DCP100A/200A Pressure
The DCT1000 system may be configured to be a self-contained on-demand control system with the installation
of the DCP100a /200a pressure module. When this module is installed, the master controller detects it and
automatically sets the system to an ondemand mode, enabling features associated with the pressure sensor.
The following subparagraphs describe the setup and operation of these pressure related features.
2-1 — High Limit Setup
The High limit Setup sets the pressure atwhich the cleaning cycle will begin. Thisvalue may be between zero and
the pressuremodule calibration pressure. Normally,the High limit should be above the lowlimit. If, however, the
High limit pressure isset below the low limit, the cleaning cyclewill begin when the High limit is exceededand
stop when the pressure falls below theHigh limit. The low limit in this case willhave no effect. Pressing both
Up and Downbuttons simultaneously and holding forabout four seconds will restore the factorysetting for High
limit to 5.0’’ w.c. [1.24 kPa].
2.2 — Low Limit Setup
The operation of the low limit mode isidentical to the High limit mode except thatthe default low limit
pressure is 3.0’’ w.c.[0.75 kPa]. The upper setable value is thecalibration pressure of the pressure moduleand
the lower limit is zero. Press the Selectbutton until the low limit indicator is illuminated.Use the Up and Down
controls to setthe limit to the desired setting. Pressing bothUp and Down buttons simultaneously andholding
for about four seconds will restore the factory default.
2.3 — High Alarm Setup
The operation of the High alarm Setup is identical to the High and low limit Setup.The High alarm
default is 0.0’’ w.c. The upper setable value is the calibration pressureof the pressure module and the
lower limit is zero. Press the Select button until the High alarm indicator is illuminated. Use the Up and
Down controls to set the limit to the desired setting. Pressing both Up and Down buttons simultaneously
and holding for about four seconds will restore the factory default.
2.4 — Low Alarm Setup
The operation of the low alarm Setup isidentical to the High and low limit Setup.The low alarm default
is 0.0’’ w.c. The upper setable value is the calibration pressure of the pressure module and the lower limit
is zero. Press the Select button until the low alarm indicator is illuminated. Use the Up and Down controls
to set the limit to the desired setting. Pressing both Up and Down buttons simultaneously and holding for
about four seconds will restore the factor default.
2.5 — Auto Alarm Reset Setup
The auto alarm Reset Setup mode allows the auto alarm reset time to be selected. This value may be set
between zero and 255 seconds. The factory default value is five seconds. When the auto alarm reset is
enabled by shorting the auto alarm reset terminal to a common terminal, the alarm will be reset after the
pressure returns to the normal range and the selected timeout period has expired.
3.0 Pressure Module Maintenance
The pressure module should require very little maintenance under normal operational conditions. However,
periodic calibration may be desirable to assure accuracy of the readings. The module may be removed and
returned to the factory for calibration.
