5.9 Programming Alarm Relays
5.9.1 Purpose
The Model 1056 24VDC (02 order code) and the AC switching power supply (03 order code) provide four alarm
relays for process measurement or temperature. Each alarm can be configured as a fault alarm instead of a
process alarm. Also, each relay can be programmed independently and each can be programmed as an interval
timer. This section describes how to configure alarm relays, simulate relay activation, and synchronize timers for
the four alarm relays. This section provides details to program the following alarm features:
Under the
Program/Alarms
menu, this screen will
appear to allow configuration of the alarm relays.
Follow the menu screens in Fig. XX to configure the
outputs.
This screen will appear to allow selection of a specific
alarm relay. Select the desired alarm and press
ENTER.
This screen will appear next to allow complete pro-
gramming of each alarm. Factory defaults are dis-
played as they would appear for an installed contact-
ing conductivity board. USP Safety only appears if
alarm logic is set to “USP”. Interval timer, On Time,
Recover Time, and Hold While Active only appear if
the alarm is configured as an Interval timer.
