Deadband (DB Control) adjustment

The deadband control adjusts the point at which a tripped alarm

resets. This point will be above the setpoint for a low type alarm or

below for a high type. The procedure for adjusting the DB control is as

follows:

1. Adjust the SET control

2. Set the deadband to maximum by turning the DB control fully

clockwise.

3. Trigger the alarm by setting the input signal to ‘full scale’ (for a high

type alarm) or ‘zero’ (for a low type alarm).

4. Set the input potentiometer to the position at which the alarm

should reset.

5. Decrease the deadband (turn control anticlockwise) until the LED

extinguishes.

6. Check that the setpoint and deadband are set correctly.
