Host Controller Board Alarm Conditions and
Corrective Action
This section lists valid alarms (errors) that originate from the Host
Controller board, including the Alarm Type (Fault or Warning), name and
reason the alarm is set ( Condition/Description ), and Suggested Corrective
Action for each. The Host Controller Status Codes ( HS Code ) and Host
Controller numbers ( HStatus ) to press on the keypad to view the current
status or alarms are also listed.
The possible Host Controller board alarms are polled individually with the
keypad command
F5 4 z , where ‘ z ’ ( z = 1..7 ) is defined by HStatus . For each
‘ z ’, the corresponding alarm message description is displayed if the alarm
exists; otherwise the message “ HS z OK ” appears.
On the User Interface, the ‘w’ or ‘f’ preceding an alarm indicates a
‘w’arning or ‘f’ault condition.
HS Code HStatus Alarm Type Condition / Description and Suggested Corrective Action
0 — — HSz OK
If the HS Code returned is ‘ 0 ’ and the message displayed is “ HS z
OK ”, it indicates that the Warning or Fault being viewed does not
exist (where ‘ z ’ is the HStatus number 1..7 assigned to that alarm).
This is not an alarm condition.
Corrective Action:
No action is required.
1 1 Warning w EEPROM Full
The EEPROM (nonvolatile memory) has exceeded the safe num-
ber of times that configuration data has been rewritten to it (95 %
used).
Corrective Action:
• Replace the EEPROM as soon as possible. Contact AMETEK
to verify operation before removing the EEPROM and for
information about installing the new EEPROM to ensure your
analyzer will operate the same as it did prior to replacing the
EEPROM.
