Western Telematic PLS-345 - Manual (Page 32)

1. Monitor Mode: Enables/disables the Monitor Mode
feature. Do not enable the Monitor Mode until you have
finished selecting the other Monitor Mode parameters.
(Default = Off.)
2. Switch If Level: Determines which line condition will
cause the selected A/B circuits to switch. This item can
either be set to "0 - Low" or "1 - High". When this item is
set at "0 - Low", the selected A/B circuit(s) will be
switched when the line goes low. When this item is set at
"1 - High", the selected A/B circuit(s) will be switched
when the line goes high. (Default = "0 - Low".)
3. Switch to Position: Determines which A/B line will be
automatically selected when the line goes to the target
level (Item 2.) For example, if Item 2 is set at "0 - Low"
and Item 3 is set at "B", then the monitored line goes low,
the selected A/B circuit(s) will be switched to Line B.
(Default = B.)
4. Delay Period: Determines how long the monitored line
must remain at the target level (Item 2) in order to trigger
automatic A/B switching. For example, if the target level
is "1 - High" and the Delay Period is 1 minute, then the
selected A/B circuits will be switched when the monitored
line remains high for 1 minute. (Default = 5 Seconds.)
Note: When Item 5 (Return) is enabled, the Delay
Period also determines how long the line must return
to (and remain at) the normal state in order for the
A/B line to be switched back to it's original setting.
