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.
Two temperature probes can be connected to the System Interface Board mounted inside the distribution cabinet. See
Two temperature probes can be connected to the IB2 (Controller Interface Board) mounted inside the distribution cabinet. See
Two temperature probes can be connected to the optional EIB (Controller Extended Interface Board) mounted inside the distribution
cabinet. See
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.
Three temperature probe inputs (System Temp 1, System Temp 2, and IB2-1 Temp 1) are factory programmed
as battery type. Battery temperature compensation and battery thermal runaway management is also factory
programmed. Install the three temperature probes included with the system into these inputs. The battery
string in the bottom tray is considered Battery #1. The temperature probe for this string should be connected
to System Temp 1. The battery string in the second tray is considered Battery #2. The temperature probe for
this string should be connected to System Temp 2. The battery string in the top (third) tray is considered
Battery #3. The temperature probe for this string should be connected to IB2-1 Temp 1.
