Dwyer Instruments DPT series Installation and operating instructions

Bulletin P-DPT
The Series DPT Digital Pressure Transmitter with Switches combines a large,
14-segment LED display with two programmable solid state switches into one
compact unit. A unique, 3-way rotating design allows the DPT to meet specific
installation requirements without any retrofitting. The display and electrical
connection can be rotated independently to maximize visibility while still orienting
the electrical connection in the best position for the cable connector. Large,
ergonomically designed push buttons allow for quick/easy programming and thin-
film piezoresitive sensor technology guarantees long-term reliability and stability.
INSTALLATION
When installing gage always use a hex at the base of the housing to tighten the
gage to a mating fitting. Do not apply wrench to housing.

BUTTON OPERATION
SWITCH FUNCTION
ERROR
Hysteresis function
If the system pressure fluctuates around the nominal value,
the hysteresis keeps the switch status of the outputs stable.
When the system pressure is rising, the output switches when it
reaches the respective set point (SP); if the pressure falls again,
the output switches back only if the reset point (RP) is reached.
Application example: loading an accumulator.
The shut-off valve loads up to 8o bar and then shuts off. When
70 bar is reached again, it switches on once more.
Window function
The window function allows the monitoring of a defined range.
If the system pressure is between the window high (FH) and the
window low (FL), the output is activated (NO) respective
deactivated (NC).
Delay times (0.00 to 50 s):
By this means unwanted pressure peaks of short duration or high
frequency can be filtered out.
The pressure must remain for at least this time to enable the
switch to operate. The switching output does not immediately
change its status when it reaches the switching event, but only
after the delay time has elapsed. If the switching event no longer
pertains when the delay time has elapsed, the switching output
does not change.

PARAMETERS
TROUBLESHOOTING
WARRANTY
Upon final installation, no routine maintenance is required. A periodic check of the
calibration is recommended. The series DPT is not field serviceable and should be
returned if repair is needed (field repair should not be attempted and may void
warranty). Be sure to include a brief description of the problem plus any relevant
application notes. Contact customer service to receive a returns goods authorization
number before shipping.
Failure Possible cause Procedure
No output signal Cable break Check connections and cable
No output signal No/incorrect voltage supply Adjust the voltage supply to correspond
with the Operating Instructions
No/False output signal Incorrectly wired Follow pin assignment (see Instrument
Label / Operating Instructions)
Output signal unchanged after change in pressure Mechanical overload through over pressure Replace instrument; if failure reoccurs,
consult the manufacturer
Abnormal zero point signal Overload limits exceeded Ensure permissible overload limits are
observed (see Operating Instructions)
Signal span too small Mechanical overload through over pressure Replace instrument; if failure reoccurs,
consult the manufacturer
Signal span too small Power supply too high/too low Correct the power supply in line with
the Operating Instructions
