CHECK FOR ALARMS
To determine what alarms are present, enter the following code:
“0 0 0”
The VRC2500 will respond:
• C
HECKING F
OR ALARMS
ON UNIT X
If no alarms are present, the VRC2500 will respond:
• N
O ALARMS PENDING ON CURRENT UNIT
The VRC2500 will also tell what mode the user is in (operator
mode or observer mode).
If alarms are present, the VRC2500 will list the alarm conditions,
beginning with the oldest alarm stored in the system. After each
alarm is reported, the following options are possible: scroll
forward and back through the alarm list using the # (forward) and
* (back) keys; repeat the alarm just reported with the 8 key; report
the current mode by entering 6* ; exit the alarm routine with 3 or
0#; or erase all alarms with 010.
Once the cause of an alarm is determined, the problem can be
corrected by issuing commands to the appropriate command
channels.
CLEAR ALARMS
To clear all alarms stored through the Dial-Up, enter:
“0 1 0”
This clears all alarms. Be careful with this command, since
alarms cannot be recalled once they have been cleared.
STATUS CHANNEL ALARMS
Status-channel alarms are generated when the sample changes
its state (e.g. a status channel sample goes low or high). For
example, if an alarm is generated and cleared, a new alarm will
not be generated until the status channel goes back to its
nominal condition then changes state to the alarm condition. The
alarm is generated by the change between high and low states.
