8. External Power (24 VDC) and 0 to 5 VDC Analog Output Option
When equipped with this option the gauge no longer operates from batteries
but instead is “externally powered”. Both the 24* VDC input power and the 0 to
5 VDC Analog Output are connected to the 6 pin circular connector on the rear
of the unit. Pin connections are as follows:
*Actual range of input voltage is 12 to 31 VDC.
24 VDC External Power and 0-5 V Analog Output
PIN -A- PLUS (+) 24 VDC POWER IN
PIN -B- PLUS (+) ANALOG OUTPUT
PIN -C- MINUS (-) ANALOG OUTPUT
PIN -D- MINUS (-) 24 VDC POWER IN
PIN -E- NO CONNECTION
PIN -F- CASE GROUND
9. External Power Without Other Options
The external power input is accessed through a miniature “Phone Jack” (mate
supplied) on the back of the unit. The “Tip” connection is “+ Power” and the
center connection is “- Power”. DO NOT CONNECT TO THE CASE
CONNECTION. This should only be used as a cable restraint.
It is important that you never remove or insert the "Phone Jack" connector
into the gauge with the power turned on. This can damage the gauge and cause
it to fail. Only turn the power on after the "Phone Jack" has been inserted into
the external power connector.
