Configuring alarms and assigning setpoints

4.4.1 Purpose of configuring alarms and setpoints
This section describes how to configure and assign setpoints to the alarm relays, simulate
alarm action, and synchronize interval timers.

alarm relay.
There are four alarm relays. The relays are freely assignable to any
sensor and to either the measurement (for example, chlorine) or
temperature. Alarm relays can also be assigned to operate as interval
timers or as fault alarms. A fault alarm activates when the transmitter
detects a fault in either itself of the sensor.
A fault condition exists when the transmitter detects a problem with
the sensor or with the transmitter itself that is likely to cause seriously
erroneous readings. If an alarm was programmed as a fault alarm, the
alarm activates. At the same time, a fault message appears in the main
display.
