16.6 Printer Messages
The master station can log alarm messages to a serial printer. Each message takes the form:
<Date> <Time> <FCU Address> <FCU Tag Name> <Alarm Text>
The alarm text printed will depend on the data bit from the comms link being present. The table shows
the text printed and the associated data bit from the block and parameter in the data base. Block and
parameter data is given in the Pakscan Modbus Interface Specification (Publication S171E).

16.7 Maintenance
The Pakscan IIE 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
and maintain the clock in the absence of mains power.
The battery is located in a holder on the main circuit board, 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 5 minutes.
