5.4 Menu Commands Overview, continued
Calibrating the CFR
The CFR-UPS may be calibrated using two sets of parameters -
Maintenance Parameters (commands “70” to “79”) and Service Parameters
(commands “80” to “89”). Maintenance parameters allow you to customize
the CFR detection and warning levels. There should be no need to change
these setting unless wider or narrower detection tolerances are required.
Transmitting Unsolicited Alarms
The UPS can automatically transmit alarm messages (in ASCII format)
to notify a status change or a power problem as it occurs. You can enable or
disable this option by using commands “510” and “509” respectively.
