GenStart

It should be noted that the Generator Start Operation is designed to minimize the generator run time, so at the

present 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‟ 11.0 (22) 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 contacts are

NEC Class 2, rated 2 amps at 24 VDC.

It should be noted that the GenStart contacts are shown in Figure 1.4-9 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.

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 values will not be recognized until this takes place.

The first 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 figure below is also available on the Rear of the Control/Display Unit.
