To reset to factory defaults, reset calibration data only or reset analog outputs only, access the Reset screen by pressing ENTER/MENU from the main screen.

5.7Programming 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 Setpoint, Interval Timer, TPC, Bleed and Feed, Water Meter, Delay timer, Date and Time, Fault or None and press

ENTER/MENU.

3.To assign a measurement to a specific relay, select the desired measurement or temperature input and press

ENTER/MENU.

4.To set relay logic to activate alarms at a High reading or a Low reading, select high or low and press ENTER/MENU.
