4-3.3.8 GenStart
It should be noted that the Generator Start Operation is designed to minimize the generator run time, so at the preset set
points there is no Absorption stage per se. Therefore, the batteries must be periodically conditioned by leaving the generator
on, or charging them with another system.
The GenStart feature is designed for use in installations where a generator is used to provide AC input power for battery
charging. The GenStart feature provides a contact closure to signal the generator to start when battery voltage falls below
the “Generator Start Volts” 12.5 (25.0) VDC setpoint. The GenStart contacts open when bulk charging current fall below the
“Generator End Amps” 20 Amp DC setpoint. The Bulk charging current is checked every 4 minutes, therefore the minimum
generator ON time is 4 minutes. The contact are NEC Class 2, rated 2 amps at 24 VDC.
It should be noted that the GenStart contacts are shown in Figure 6 - Customer Terminations, and likewise a similar set of
Normally Open Contacts are available to indicate a “Low Battery” or “Fan On” condition.
CAUTION!!
The battery charging process will be affected if 12 (24) VDC loads are being
powered during battery charging. The increased charger output, required to power those loads,
may keep the charger from reaching the “Generator End Amps” setpoint.
4-3.3.9 Charger and APM Programming
The chart below shows the control switch settings for programming the ITC Charger and APM settings.
NOTE: It should be noted that the power switch on the front of the unit must be cycled to
read in the new Control Switch settings into memory. The new vales will not be recognized until
this takes place.
The fi rst 4 (1-4) switches program in the Maximum Charger Current and the next 4 (5-8) program in the APM Current Limit.
The next switch (switch 9) is for selecting either Wet or Gel type batteries.
The next switch (switch 10) is reserved for future expansion.
The next switch (switch 11) is reserved for future expansion.
The next switch (switch 12) is reserved for selecting a Master/Slave remote with multiple Control/Display Units.
NOTE: The fi gure on next page may be available on the Rear of the Control/Display Unit
depending on model.
