OPEN-ALL-CHANNELS
Selecting OPEN-ALL-CHANNELS will immediately open
any closed scanner card channel(s).
■
CLOSE-CHANNELS
Selecting CLOSE-CHANNEL will display the following
message prompting you to select the channel to close:
ENTER CHAN#01 (1-10)
The field entry after “ENTER CHAN#” indicates the chan-
nel to close. To close a channel, simply use the cursor and
range keys to select the number of the channel to close, then
press ENTER. The number of the closed channel will be dis-
played on the front panel along with normal readings. Keep
in mind that channel 1 is the reference junction.
Selecting a different channel from the one that is presently
closed will cause the closed channel to open and allow a set-
tling time before closing the selected channel.
Channel relays will be closed according to the presently
selected function. If a 2-wire function is used, only the relay
for that one channel will be closed. If a 4-wire function is
selected, both the selected channel relay and the matching
relay pair will close. For example, closing channel 2 will also
close the channel 7 relay. Fixed 4-pole relay pairs are:
• 2 and 7
• 3 and 8
• 4 and 8
• 5 and 10.
