5.7 Programming Alarm Relays
The T56 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 or one
of four advanced timer functions. 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. To program
the alarm relays, access the Program
screen by pressing ENTER/MENU from the
main screen and then select the Relay tab
and the Configure relay control.
The following relay functions can be programmed to any relay from the Configure Relay
screen:
1. assign a relay
2. define a relay function
3. assign a Measurement
4. set relay logic
5. enter setpoints
6. set deadband
7. set normal state
8. set USP Safety level (contacting conductivity)
To program these relay functions, access the Configure Relay screen by pressing ENTER/MENU
from the main Relay programming screen.
1. To assign a relay, highlight the desired
Relay 1-4 and press ENTER/MENU.
2. To define a relay function, select from
