CleaverBrooks Hawk 1000 - Actuator Selection

Hawk 1000 Section 4 — System Configuration
Part No. 750-366 4-17
Communications failure is detected, an alarm message “Remote Communications Failed” is displayed on the
HMI and Setpoint reverts back to the LOCAL setting on the HMI
Dual Set Point
Dual Set Point control - traditionally referred to as night setback - allows the Boiler Controller to easily switch
from the primary set point (Set Point 1) to the setback set point (Set Point 2). Set Point 1 is the primary set
point for the Controller and is the only set point available if the Dual Set Point option is disallowed (see below).
Setback can be initiated manually (through the HMI on the Firing Rate screen) or remotely (by energizing an
isolated contact input signal (120 VAC) on digital input I:5.14. Press the button to the right of “Dual Set Point
Selection By” to toggle between <HMI Input> and <Digital In>.
The Dual Set Point option is not allowed when Remote Modulation, or Remote Set Point options are enabled.
Selecting <Yes> to Dual Setpoint enables dual Set Point control. This option is not allowed for low emission
steam boilers (<60 ppm).

Warning
Remote Set Point control should not be used on certain Low
Emission boiler systems. Low Emission boilers can be
sensitive to
changing operating set points. Contact your Cleaver-Brooks
representative to determine if Remote Set Point control is allowed on
your boiler. Failure to follow these precautions may result in
damage to equipment, serious personal
injur y , or death.
