POWER FAIL BACKUP
Non-Volatile Memory keeps time and programs for indefinite power outages. All outputs and the
display are disabled during backup. The MC22LV resumes normal operation when power returns.
If the master clock has been without power for more than 48 hours a “Unit Power Fail” message
will appear when power is restored. Times and program will be intact, however pressing the [3]
key will begin the AUTO PROMPT sequence. Check time, date, day, etc. to insure accuracy, then
press the [EXIT].
ACCURACY
Time Keeping - Synchronous with the AC power line. During a power failure, or when crystal time
base is selected, timekeeping is crystal controlled with an accuracy of +/- 4 PPM throughout its full
temperature range.
Programmed Events - On/Off events are programmable with a one-minute resolution and occur
at the zero second of that minute.
Operating Temperature Range - 0 to 50 degrees C
PHYSICAL
MC22LV: Black, painted aluminum enclosure - 4.8"W X 8"H X 1.8"D.
