SMART RELAY SREL, SREL.ZK, SREL.ADV

9.0 Maintenance

9.1 BATTERY WARNING AND BATTERY REPLACEMENT WHEN THE BATTERY

SREL.BAT IS USED

A Smart Relay can emit a battery warning as follows when the battery capacity is de-

pleted:

SREL, SREL.ZK, SREL.ADV

 Inside LED flashes 8x each time a transponder is used and before the relay

switches.

 This LED should be visible from the outside in the case of battery-powered

operation.

SREL.ADV only

 External LED flashes 8x or external buzzer beeps 8x each time a transponder

is used.

Around another 100 transactions are possible after a battery warning; the bat-

tery should thus be replaced as soon as possible.

9.2 BACKUP BATTERY

A discharged backup battery may lead to the internal clock stopping in Smart Relay

types SREL.ZK and SREL.ADV. We therefore recommend checking the time on the

clock at regular intervals. A backup battery will last for about ten years if the power

supply to the Smart Relay is not interrupted. If Smart Relay draws on the backup bat-

tery at regular intervals due to frequent power failures, this battery should be replaced

on a periodical basis.

If Smart Relay is powered by a battery (SREL.BAT), the backup battery must not

used.
