Alarm Programming
Overview
The meter is equipped with four alarm points as a standard feature.
Each alarm may be programmed for either a high or low alarm and
for 0-100% deadband. Front panel LEDs indicate alarm status.
Options for two or four relays are available.
To program a high alarm, program the set point above the reset point.
To program a low alarm, program the set point below the reset point.
To program the alarm deadband, set the reset point above or below
the set point by an amount equal to the desired deadband value.
Example: Alarm 2 is a high alarm that trips at 1500 and has a dead-
band of 100. Alarm 2 set point is set at 1500 and its reset point at
1400.
