SET-ATTR::SYS:TS1000::ELEVTIME=ENABLE;

This command allows alarms to automatically escalate to the next higher alarm 
level after the time period specified in the FLTDELAY keyword has elapsed (see 

, on page 130, for more details).

SET-ATTR::SYS:TS1000::EXPFAIL=NA;

This command disables the Expansion Fail alarm that occurs if you are not using an 
Expansion Panel with the TimeProvider.

You use the ED-SYNC command to provision system-level alarms. The CLRDELAY 
and FLTDELAY parameters are system-wide; the parameters cannot be set for 
individual alarms.

ED-SYNC:[<tid>]:<aid>:[<ctag>]::<keyword>=<value>;

This command has a default access level of ADMIN.

Note:

1

When the fault is detected, the input is immediately removed from the possible reference
list. The fault must be continuously present for the period specified by FLTDELAY before
the alarm is set. After the alarm is set, it clears once the input signal is fault-free for the
period specified by CLRDELAY.

2

Once INPFREQ is set, the alarm clears when the input frequency is within the defined
pull-in range
