12.9 Maintenance

The Pakscan IIS master station is not suitable for field repair. Should the unit require maintenance contact
your local Rotork representative.
Battery Replacement
The master station contains a long life battery that should last for at least 3 years when no power is applied and
considerably longer in normal use. Should the battery deteriorate a warning is displayed on the master station
opening status screen. (The 'B' alarm may sometimes be generated on power on and can be cleared. This is
normal for the unit.) The battery is used to retain the parameter settings, clock and sequence programmes in
memory in the absence of mains power.
The battery is located in a holder on the main circuit board and it can be replaced by levering out the old
battery and pressing in the replacement.
In the absence of both the battery and mains power an on board capacitor will maintain the memory data for at
least one hour. In addition, basic setup data, such as port setups and addresses are held in non-volatile
EEPROM.
