Battery Temperature Probe
This system can be used with one or more Battery Temperature Probes. Probe must be mounted near or on the
battery to sense battery temperature. Probes connect the MCA and allows it to:
• Automatically increase or decrease system output voltage to maintain battery float current as battery
ambient temperature decreases or increases, respectively. Battery life can be extended when an
optimum charge voltage with respect to temperature is maintained.
• Issue alarms if battery temperature increases above or decreases below preset adjustable limits.
Each Distribution Cabinet provides connections up to four (4) Battery Temperature Probes. Refer to
SAG589200100 for probe specifications and ordering information.
Load Shed Card (Part No. 528927)
Features
♦ Provides eight (8) relays that can be individually configured as additional alarm relays or as
Low Voltage Disconnect control relays for reducing the system load (load shed). If
configured for load disconnect, control of the relays can be based upon either system
voltage or battery discharge elapsed time.
♦ Provides four (4) battery midpoint monitoring inputs.
♦ All functions are configured and controlled by the system MCA.
♦ External mounting.
♦ Includes one (1) 2 ft. MCA control bus cable (P/N 524410) and one (1) control bus
termination plug (P/N 524653).
♦ See
for Load Shed Card dimensions.
♦ See Load Shed Card Installation and Operating Instructions (Section 5985) for complete specifications.
Restrictions
Load shed contactors are not included.
A system battery shunt is required for timed Load Shed.
MCA version 3.0 or newer is required.
Maximum number of Load Shed Cards supported by MCA is four (4).
Maximum combined MCA control bus cable length must not exceed 125 feet.
Ordering Notes
1) Where MCA control bus cable lengths other than the furnished 2 ft. cable are required, order per
