Deadband(DBControl)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 as above.
. Set source B to 4 mA.
. Set the deadband to maximum by turning the DB control fully
clockwise.
4. Trigger the alarm by setting source A to 0 mA (for a high type
alarm) or 4 mA (for a low type alarm).
. Set source A to give the differential current at which the alarm
should reset.
6. Decrease the deadband (turn control anticlockwise) until the LED
extinguishes.
. Check that the setpoint and deadband are set correctly.
