This module is only used with Programmed Start, Rapid Start or Programmed Rapid Start style ballast.
THE ELA PSPRSB IS NOT USED WITH INSTANT START STYLE BALLAST.
THE ELA PSPRSB IS NOT USED WITH THE POWER SENTRY PSSD
THE ELA PSPRSB IS NOT USED WITH THE PS300 SERIES OF BATTERY/INVERTERS.
Its purpose is to add a 5 to 8 second delay to regular AC power being returned to the ballast when the fixture is returning to regular AC operation when coming out of emergency operation. This time delay is required at times due to the EOL (End Of Lamp) circuitry that the ballast uses in its internal circuitry. The EOL circuitry in the ballast reacts quicker than the battery can turn off. When the EOL circuit checks the lamp to see if it is a good lamp for the ballast to try and ignite, it sees the DC signal from the battery at the lamp and shuts the ballast down, as it thinks the lamp is bad. The time delay of 5 to 8 seconds that the ELA PSPRSB adds to the power being returned to the ballast, gives the battery signal time to dissipate so that the EOL circuitry never sees the DC signal.
If the unit operates correctly without the ELA PSPRSB it may be that the ballast has incorporated this time delay into its circuitry. Removing the ELA PSPRSB from the unit will cause no harm and does not affect the Power Sentry product warranty. To bypass the ELA PSPRSB unplug the ELA PSPRSB from the Power Sentry battery pack.
(1) Unplug the test switch/pilot light from the ELA PSPRSB.
(2) Plug the test switch/pilot light directly into the four pin connector of the Power Sentry product it is being used with.
(3) Test the fixture for proper operation in regular and emergency operation.
