A deviation band alarm controls relay action symmetrically around a setpoint. The relay actuates
when the reading falls within the deviation band, and de-actuates when the reading falls outside. A
deviation value (such as 50 counts) is set up around both sides of the setpoint to create the
deviation band. Passbands around a setpoint are often used for component testing.
Control Input 1 causes a master reset when tied to ground if selected to do so with the
Control
Inputs
drop-down box under the
Relay Alarms
tab. This resets latched alarms and the analog
output. Control Input 2 is not used with the serial input transmitter.
