When adjustments are complete and before putting the Element into service, return the MAN
OVR function to “AUTO”. Failure to return the MAN OVR function to “AUTO” can cause high
water temperatures that can result in property damage, scalding, other serious injury or death.
11.5.11 Potentiometer (Operating Setpoint for Standalone Operation)
The PIM Ignition Control will continue to operate the Element at a 120° internal setpoint should
the touch screen control fail, or communication between the two devices is interrupted. This
internal setpoint can be adjusted using the potentiometer to maintain a different operating
temperature under these circumstances if desired. This feature is intended to be used on a
temporary basis, since accuracy of temperature control is dependent upon the touch screen
control.
IMPORTANT
: At the time of commissioning, It is recommended that the startup technician
adjust the potentiometer to desired setpoint displayed in the
OPERATOR
screen located in the
SOURCE
control system menu. The standalone setpoint can be adjusted independently of the
touchscreen but a specific setting may be difficult to achieve on the PIM.
NOTE:
If the operating setpoint is ever changed after initial commissioning, the potentiometer
should be readjusted as well.
