MANUAL BATTERY TESTING
PREPARATION -
Proper precautions must be taken when performing battery testing. The load(s) should be available
to test on inverter, in a loss of power simulation. Be sure also to take precautions to have the load(s) in a mode
that could to
lerate a shut down.
If the battery test fails the system may shutdown and all of the loads connected to
it will lose power.
It is recommended that batteries are periodically inspected for corroded and loose connections. Battery connections
should be tightened annually by qualified electrical personnel. Batteries should be checked as indicated by monthly
battery testing.
MANUAL BATTERY TEST
GENERAL
- The inverter is preset at the factory for a 30 second manual battery test. During the test, the battery
discharge rate is evaluated to determine the health of the battery string.
Testing Procedure:
1. On the Intellistat TS
TM
Monitor, select “Test” from the Main Menu. Enter the required password to continue. Select
“MANUAL” from the menu and when the next screen appears push the green TEST button. This will force the
inverter into battery mode for the programmed duration (30 seconds).
2. The unit will stay in battery mode for the pre-programmed duration and then return to normal mode. You will
have the option to abort the test if required. See
“Operation - Intellistat TS
TM
Monitor - Manual Battery Testing”
.
3. If the health of the battery string is suspect, a general alarm will exist on the Intellistat TS
TM
monitor and the
general alarm will continue to exist after the battery test is complete. By going to the ALM LOG screen on the
Intellistat TS
TM
Monitor a BATTERY TEST FAIL indication will be displayed in the TST LOG screen. A contact
closure signal is also provided as a result of the general alarm status. The general alarm signal may be used
for external / remote communications. See
“Dip Switch and Alarm Terminal Setup”
or
“Option Interconnection
Diagram”
for details.
