Fault finding
CAUTION
If cooling water has been interrupted whilst the pump is in operation, do not restore the cooling until the pump
has cooled down to a safe temperature. Restoring the cooling water supply whilst the pump is in operation may
result in FDP seizure.
Before performing any maintenance or trouble shooting it is recommended that you follow the lockout/tagout
procedures according to the Control of Hazardous Energy (Lockout/Tagout) in Volume 29 of the Code of Federal
Regulation (29CFR) Section 1910.147 for the customer supply.
6.17.1
Warning and alarm message fault finding
When a warning or alarm message is generated, you can display the message and (for some of the messages) two lines
of text (the advisory message) which identify possible checks you can make to identify the cause of the fault and to
rectify the fault.
The first line of a message specifies the fault condition (warning or alarm) and shows the error number. Error numbers
are of the form PFF, PPFF or PPPFF, where:
P, PP, or PPP specifies the fault parameter associated with the alarm or warning: refer to Table 18. Note
that Table 18 defines all of the possible sources; some of these may not be fitted to your iF system.
FF specifies the fault type: refer to Table 22.
Table 18 shows all of the warning messages, the corresponding lines of advisory text (if any) and the meaning of the
error/recommended actions. The warning messages are given in error number order in this table.
Table 19 shows all of the alarm messages, the corresponding lines of advisory text (if any) and the meaning of the
error/recommended actions. The alarm messages are given in error number order in this table.
Note that Tables 18 and 19 show all of the possible warning and alarm messages, however some of these messages
may not be displayed: this depends on how you have adjusted the setpoints.
6.17.2
Other fault finding
Fault messages will be shown on the Pump Display Terminal to identify that the action you have selected cannot be
carried out. The messages which can be displayed and their meanings are shown in Table 20.
