Volts – Free Relay
Battery Temperature Compensation Sensor
Fig. 3.2a SM35/36 Monitor Cabling
For S
M35/36 Relays 1‐ 6 can be used for normally open or normally closed states by jumper
selection. The relay states labelled NO or NC is for their de‐energized state.
If an alarm is programmed for the relay to be normally energized (as may be required in the
case of a low voltage alarm where loss of power will put the alarm into its active state), then be
sure to connect the remote wiring appropriately.
For full monitor functionality and operation information, refer to the appropriate monitor manual.
Temperature Sensors
Uncoil the battery temperature sensor tie wrapped to rear of shelf and place in the middle of the
middle battery string. If the lead is not long enough, ordinary 2-core copper (approx. 18
2
AWG/0.75mm
) wire can be used as an extension. The purpose of the battery temperature
sensor is to monitor the ambient temperature of the batteries over long periods of time and
adjust the rectifier output (float) voltage accordingly. As a result, it is not necessary to have the
temperature sensor touching the batteries. If the Battery Temperature Sensor is removed a
"battery temp fault" alarm is generated.
The "Ambient" temperature sensor (optional) can be used to monitor the temperature in another
location if required.
Connecting via Computer
For remote communications and direct computer connection to the Compact System, refer to
the SM36 Manual. These connections can be made via the mini-USB port on the front panel of
the monitor (computer connection to the SM36, USB cable included) and the Ethernet port
(SM36 web-based communications only). The Ethernet port has been extended to the rears of
the shelf via a patch cord and RJ45 coupler for installer convenience.
When a laptop/pc is connected for the first time to the SM36, the USB drivers will have to be
installed on the connected computer. See the SM36 manual for details.
Help files can be accessed for a field by left clicking inside the field and pressing the F1
key on the keyboard. Example shown in Fig. 4
