Series DPT Digital Pressure Transmitter with Switches

Specifications - Installation and Operating Instructions

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 thinfilm 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

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.

Error Display Description

ATT1 On changing the Switch Point the system automatically reduces the Reset Point

ATT2 Zero Point adjustment error, current pressure is outside the limits

ATT3 Password entered for Menu access is incorrect

ERR Internal error

OL Overpressure, measuring range exceeded > approx. 5% (Display blinks)

TROUBLESHOOTING

Failure Possible cause Procedure

No output signal Cable break Check connections and cable

No output signal No/incorrect voltage supply

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.
