Set the dry contact parameters, as shown in
Issue 10 (2015-09-15)
By default, 0.1C EOD (V/cell) is set to 1.80, 0.3C EOD (V/cell) to 1.75, 0.5C EOD
(V/cell) to 1.67, and 1.0C EOD (V/cell) to 1.60. These values are calculated in real time
based on the discharge currents.
Intelligent hibernation
If this parameter is set to Enable, the intelligent battery hibernation function is enable.
Class 1 grid hiber. time (d) and Class 2 grid hiber. time (d)
Set the hibernation time based on the power grid type. In hibernation mode, batteries are
not charged or discharged, which extends the battery lifespan. The Class 1 grid hiber.
time value range is 0–30 days, and the default value is 13 days. The value 0 indicates no
hibernation. The Class 2 grid hiber. time value range is 0–15 days, and the default value
is 6 days. The value 0 indicates no hibernation.
Chg. volt. over range point(%) and Dis. volt. over range point (%)
The parameters check whether the batteries in each battery string have the same charge
voltage and discharge voltage. When a value exceeds the specified range, an alarm is
generated.
The calculation formula is: (Charge/Discharge voltage – Average voltage)/Average
voltage x 100%.
Set the dry contacts that you need to use. Otherwise, the UPS may not run properly.
When you disable a dry contact card, its dry contact signals are disable.
After you enable a dry contact card, its dry contact signals can be displayed on the LCD.
Disable all the dry contacts for a dry contact card that is not connected and all the dry
contacts that are not used to prevent false alarms.

Dry contact card (MUE05A): provides dry contact signals for the battery grounding
failure detector, D.G., BCB box, and PDCs.
Backfeed protection board (MUE06A): provides backfeed protection signals. You need
only to enable or disable this board.
Monitoring interface card (MUS05A): provides four routes of configurable output dry
contact signals.
Dry contact extended card (MUE07A): provides two routes of input signals and one
route of output signals.
