DPA/RES

•

Operation

General

The DPA/RES allows you to set two independent trip points against

the measurement taken by a resistance based sensor. They are

specially built and calibrated to suit the resistance range ordered. Note:

if the lead length resistance is likely to be significant when installed,

then the unit should be calibrated on site for the most accurate results.

Setup

The alarm relay coils operate according to each setpoint/deadband

configured via front panel multiturn potentiometers. Internal push

fit jumpers determine the alarm type (high or low acting) and coil

energisation (normally energised/de-energised).
