Back-up battery
In order to maintain the data of the operational data (e.g. error protocol, data of the
PN program, … ) a rechargeable lithium battery is located in every CPU module of
the version PSC-CPU-OP-MON (the user program is stored in a non-volatile
manner in a flash). The connection is made via a 3 pole plug. It has a service life of
approximately 5 years. Approximate
ly 4 hours’ operation per day are required to
achieve an adequate charged state. Data is then for secure for over 1 year (at
25°C) if the PROTECT-PSC is in a de-energised state.
The battery voltage is monitored by the CPU module. If the voltage drops below a
minimum level, a battery alarm is given (error code 022). If the battery alarm
continues to exist after a charging period of 8 hours, the battery must be replaced.
