BATTERY BACKUP (SEE ALSO GENERAL SPECIFICATIONS FOR OVER- ALL UNIT) 1. Batteries used: (2) Panasonic LCR12V 3.4P 12V, 3.4Ah OR (2) Powersonic Model PS-1230 l2Volt, 3.OAh 2. Startup voltage: 20.4V Battery voltages below 20.4 volts indicate batteries hooked up wrong or damaged batteries. Charger will trickle charge at a rate of 10ma if it detects a battery voltage of below 20.4V 3. Battery recharge time: About 8 hours Recharg ...

SECTION 9.0 - BACKUP OPERATION 1. The battery backup system utilizes two sealed lead acid batteries which must be maintained in a fully charged state to ensure proper auxiliary operation. The charging circuitry charges the batteries whenever the roller appa- ratus is plugged in and power is applied to it. The charg- ing circuit will charge the batteries even if the power switch on the roller apparatus is in the Off position. 2. If primary power is lo ...

Batteries pulled from stock should have a full charge when new. 10.1 CI ...

ROTATION ALARM SYSTEM (SEE FIG. F) 1. Rotation Failure Detection Method: Magnetic Reed Switch Four magnetic reed switches are located at the farthest end of the main drive belt train, two for each half of the roller rack. Magnets embedded into plastic pulleys close the magnetic reed switches as they pass during normal rotation. 2. Time between rotation failure and user notification: 3 minutes The Rotation Alarm System will no ...
