This screen is used to enable the system’s optional low voltage disconnect
circuit and set its operating parameters.
If one or more low voltage disconnect contactors were provided on your
system, proceed as follows:
•
In the General box, select the Disconnect Mode in the drop-list menu; the
choices are “LVD1 on Time, LVD2 on Time”, “LVD1 on Voltage, LVD2
on Voltage”, “LVD1 on Time, LVD2 on Voltage” or “LVD1, LVD2 and
LVD3 on capacity”. Factory default is “LVD1 on Voltage, LVD2 on
Voltage”.
Note 1:
The LVD1 and LVD2 contactors are connected to the J7 and J8
connectors respectively on the controller interface card as illustrated in
Note 2:
If a 3
rd
LVD contactor is used, it must be connected to an output
relay. The LVD3 can be enabled only if “LVD1, LVD2 and LVD3 on
capacity” is selected in the Disconnect Mode in the drop-list menu.
•
In the General box, if it is necessary to modify the Reconnect Level
threshold, enter the desired value in the field above the
button,
and then click on the
button to confirm the new value.

In the LVD1 box, verify that the low voltage disconnect function is
enabled:
. If the function is disabled
(
), click on the
button to enable the function.
•
In the LVD1 box, if the “LVD1 on Voltage, LVD2 on Voltage”
disconnect mode was selected above and if it is necessary to modify the
Disconnect Level threshold, enter the desired value in the Disconnect
Level field above the
button, then click on the
button to
confirm the new value, or
•
In the LVD1 box, if the “LVD1 on Time, LVD2 on Time” or “LVD1 on
Time, LVD2 on Voltage” disconnect mode was selected above and if it is
necessary to modify the Disconnect Delay threshold, enter the desired
time in hours in the Disconnect Delay field above the
button, then
click on the
button to confirm the new value.
•
In the LVD1 box, if the
“
LVD1, LVD2 and LVD3 on capacity
”
disconnect mode was selected above and if it is necessary to modify the
Disconnect Capacity threshold, enter the desired time in hours in the
Disconnect Capacity field above the
button, then click on the
button to confirm the new value.
•
If a 2
nd
LVD contactor was provided, in the LVD2 box, repeat the four
steps performed for the LVD1 box above.
