SPECIFICATIONS
TERMINAL BLOCK #15
This output becomes active for the overvoltage light (high voltage) or for high
idle control (low voltage) dependent on the setting of SW1 switch 3 .
OVER-VOLTAGE INDICATOR
Activates at and above 15.0 VDC and deactivates below 15.0 VDC.
HIGH IDLE CONTROL
The output will activate when the voltage drops below 12.8 VDC for more
than 1 minute. The output will remain ON for a minimum of 5 minutes
and
until the voltage exceeds 12.8 VDC.
NOTE: This output must only be used in conjunction with the appropriate
safety interlocks for the intended application.
AUXILIARY BATTERY
When an auxiliary battery is present and the system is configured for it, The
System Manager will monitor the auxiliary battery. Output (TB #7) is turned
on when the battery voltage drops below 11.9 VDC for more than 10 sec-
onds. The output will remain on until the isolated battery voltage is greater
than 11.9 VDC. If the main battery bank voltage exceeds 13 VDC, the output
will deactivate and the system will then recheck the isolated battery voltage
after a short delay. This allows the system to become part of a battery sepa-
ration solenoid system.
NOTE: When configured to monitor a second battery source, only 6 loads
can be controlled as output #7 is utilized for the isolated battery
indicator. All other functions are unchanged.
LOW VOLTAGE WARNING OUTPUT
Output from T8 is disabled when the monitored voltage is above 11.9 VDC.
At and below this level, the output will turn on to indicate low voltage.
