5000/5100 Series Digital Analog Clocks Installation and Operation Manual 29
Chapter 2: ADC-5100 Series Analog Digital Clocks
This method assumes that the local time reference is 12:00:00. The
hands are manually set to the required offset time (according to
Table 2-13 on page 29) and the microprocessor is then reset. This tells
the microprocessor that the hands are at the 12:00 position, whereas in
fact they are set to the offset time. When timecode is applied, the clock
will set itself to the correct offset time. To set an offset, follow these
steps:
1. Disconnect the timecode input.
2. Enter the Manual Set Mode by pressing and holding the
MANUAL
SET
button until the hands come to a complete stop and the error
LED at the bottom of the clock face is illuminated.
3. Set the hands to the offset time using the
CW and CCW buttons as
described in “Repositioning the Hands” on page 28. (For example,
to apply a + 4 hour offset, set the hands to 4:00. If the hands are a
long way off, the process may take up to 15 minutes. A short cut
method is described in “Hands are Offset” on page 32.)
4. Once the hands are positioned at the appropriate time, press and
hold the
MANUAL SET button until the error LED flashes. While
still holding the
MANUAL SET button, press and hold the CCW
button to reset the microprocessor. Once the LED extinguishes,
release the
CCW button and then the MANUAL SET button.
5. Re-connect the timecode. The hands should move to the correct
offset time.
Table 2-13 lists local offset programming settings:
