Deadband
The DEADBAND value is the difference, in units, between
when the switched output energizes and de-energizes. The
DEADBAND operation will change based on the selected
SWITCH MODE to be either positive (above) or negative
(below) the set point.
The deadband value is always set as a positive number (no
negative values).
•
In High Limit Alarm and High Limit Shutdown mode, the
deadband is below the set point.
•
In Low Limit Alarm and Low Limit Shutdown mode, the
deadband is above the set point.
TO DISPLAY THE DEADBAND VALUE
To display the deadband value, press the
ò
arrow key:
X.XXX psi
Deadband: X.XXX
TO SET THE DEADBAND VALUE
1. First display the DEADBAND value by pressing the
ò
arrow key.
2. Simultaneously press and hold the
ï
and
ð
keys. A
cursor will flash on the display.
3. Use the
ï

NOTE:
If the product remains in the EDIT mode, and there is
no keypad activity for approximately 30 seconds, the unit returns
to the normal operating mode and new data is not saved.
NOTE:
Consider the SWITCH MODE and operating range
when determining set point and deadband values to ensure that
the reset value is within the operating range. For example, if the
unit is operating in a High Limit Shutdown Mode, the set point is
25 psi and the deadband is 30 psi, the output will trip OFF but
never reset.
