Tyco 4100U - Manual (Page 104)

6-4
The range of possible temperatures under which the SPS may function are between 0 ° C
and 50 ° C (120° F).
The SPS operates normally under non-condensing humidity conditions up to 93% with
relative humidity at 32° C.
This section contains information about SPS jumpers, DIP switches and potentiometers.
P2: If the SPS IDNet outputs are being used, you may change P2 to configure the IDNet
shield connection.
• Position 1 – 2 (bottom ): Connects the shield to 0 V (default).
• Position 2 – 3 (top): Connects the shield to earth ground.
P3: City Card and Relay Card operation
• Position 1-2 (top): Install in pos. 1-2 only if a relay card 4100-6033 is installed and
has relay 3 programmed for operation other than "Fault (Trouble)"
• Position 2-3 (bottom): (default) For use with 4100-6033 if relay 3 is programmed for
"activate on fault (trouble)" operation. (This option is used for Brigade connection)
P1: Earth connect jumper.
• Position 1 – 2 (rhs): Enables Earth fault monitoring. Set to this position unless the
system uses a TrueAlert Power Supply under common 0 V.
• Position 2 – 3 (lhs): Disables Earth fault monitoring. Set to this position only if the
system uses a TrueAlert Power Supply under common 0 V.
Refer to Appendix A to set the device address for the SPS with DIP switch SW1.
There are two 4mm (i.e. small), potentiometers on the 4100-9848AU SPS, situated below
the centre of the pcb. These are adjusted in the factory and typically, will not need
adjusting in the field.
If it is required to adjust them, turning the potentiometer clockwise increases the voltage.
R341 Battery Charger Voltage
Adjust this potentiometer to achieve a charger voltage of 27.3V
± 0.1V at 20°C.
(Allow -36V/ °C for temperatures different to 20°C).
R342 Voltage Measurement Calibration
Adjust this potentiometer to match the measurement of charger voltage on the panel LCD
with that on a calibrated voltmeter measuring the charger output. Use the “Card
Status”option of the menu. Match the two readings to within 0.05Vdc.
