Section 5: SetUp and Configuration

5.Return: When enabled, the Monitor Mode will return the switched A/B circuit(s) to the original A/B position if the monitored signal also returns to its normal state.

(Default = Off.)

For example, assume the Monitor Mode is configured as follows:

￿Switch if Level: 1 - High

￿Switch to Position: B

￿Return: On

If the circuit starts in position "A", and the monitored line goes high, then the circuit will be switched to the "B" position. However, since the Return feature is enabled, if the line later returns to the "low" state, the circuit will also be switched back to the "A" state.

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.

6.Circuits to Switch: Determines which of the PLS's three switched A/B circuits will be controlled by the Monitor Mode. Note that when this item is used to enable the Monitor Mode at a given A/B circuit, then the Circuit Status Screen will display an asterisk in the "MON" column for that circuit. To choose the circuits that will be controlled by the Monitor Mode, proceed as follows:

a)From the Monitor Mode Parameters Menu, type 6 and press [Enter]; the PLS will display a menu that lists all three available A/B Circuits.

b)Key in the number for the desired circuit, and press [Enter]; the PLS will display another menu which allows you to include or exclude the circuit from the Monitor Mode.

c)To assign the circuit to Monitor Mode, select "On", to remove the circuit from Monitor Mode, select "Off".

After you have finished selecting parameters for the Monitor Mode, make certain to return to Item 1 in the Monitor Mode Parameters Menu and enable the Monitor Mode feature. The Monitor Mode will not function unless it has been enabled.
