Remote Start of Auto-Zero
The Auto-Zero can also be initiated by a remote, dry (potential free)
contact closure connected to Digital Input 2, Pins 10 and 11 on J108 of
the Termination board (Figure 4-8). The contact must remain closed for
at least 2 seconds (up to 5 seconds). A remote start of the Auto-Zero resets
the AZInt Timer to its initial value. The start of the next Auto-Zero will be
timed from the beginning of the remote start.
Example:
The AZInt Timer is set at 2 hours, the time remaining until the next timed
Auto-Zero is 30 minutes, and the Auto-Zero is started by a contact closure.
This will reset the AZInt Timer and the time remaining until the next
timed Auto-Zero remains 2 hours. If a timed Auto-Zero is in progress, the
remote-contact closure will be ignored.
