ALARMS
Each type of the DMP200 series has four software alarms. These can be configured by the userfor alarm type, setpoint, on/off delay and on/off hysteresis value. Alarms can be individually set
to be latching or non-latching and to flash a message on the front panel display when active.
Any of the four software alarms can operate a relay (models DMP220 and DMP240 only). In
addition a special AND function allows a relay to switch only if two or more alarm conditions are active. >
2 off single change over (form C) contacts. Rated 1A @ 250Vac 5A @ 30Vdc >
(DMP220 AND DMP240 ONLY) Relays can be configured to be energised or de-energised in the alarm condition. >
DIGITAL STATUS INPUTS
One or more of the stated functions can be user assigned to either of the two digital inputs >
(DMP230 AND DMP240 ONLY) which can be activated by external volt-free contacts:
Tare, auto zero, display hold, display maximum, display minimum, display average, display test, Reset max/min & average (to the current measured value), alarm disable, alarm acknowledge, analogue output hold, keyboard lock. >
