Refer to the ACU+ Instructions (UM1M820BNA or UM1M820DNA400) or NCU Instructions (UM1M830BNA) for
programming information.
Relay Ratings: Refer to the following.
a)
1A Steady State @ 30V DC.
b)
3A Peak @ 30V DC.
The relays may be preprogrammed for specific functions. Refer to the configuration drawing (C-drawing)
supplied with your system for your system’s specific configuration.
Temperature Probes
NOTE!
Each temperature probe consists of two or three pieces that plug together to make a complete
probe. See SAG582127000 for part numbers and descriptions.
Temperature probes can be connected to each IB2 (Controller Interface Board) and/or EIB (Controller
Extended Interface Board) mounted inside the distribution cabinet. See
Each IB2 and EIB board allows for the connection of two (2) temperature probes. Any combination of the
temperature probes can be programmed to monitor ambient temperature and/or battery temperature. A
temperature probe set to monitor battery temperature can also be used for the rectifier battery charge
temperature compensation feature, or the battery charge temperature compensation feature can be
programmed to use the average or highest value of all battery temperature probes. The battery charge
temperature compensation feature allows the controller to automatically increase or decrease the output
voltage of the system to maintain battery float current as battery temperature decreases or increases,
respectively. Battery life can be extended when an optimum charge voltage to the battery with respect to
temperature is maintained. A temperature probe set to monitor battery temperature can also be used for the
BTRM (Battery Thermal Runaway Management) feature. The BTRM feature lowers output voltage when a high
temperature condition exists to control against battery thermal runaway.
The temperature sensor end of the probe contains a tab with a 5/16” clearance hole for mounting.
A temperature probe programmed to monitor battery temperature should be mounted on the negative post of
a battery cell to sense battery temperature. A temperature probe used for battery charge temperature
compensation and/or BTRM (Battery Thermal Runaway Management) should also be mounted on the negative
post of a battery cell. A temperature probe programmed to monitor ambient temperature should be mounted
in a convenient location, away from direct sources of heat or cold.
