Three LED’s also enables a visual evaluation of the functions ofTSP-BCM12, TSP-BCM24(A) and TSP-BCM48(A), mains and
battery directly on site and are in parallel to the signal relay contact.
3.1.1 DC-IN-OK LED:
The DC-IN-OK LED is a green colour LED that indicates the presence of the input voltage.
3.1.2 BATT-OK LED:
The BATT-OK LED is a green colour LED that indicates (if lit) the battery can supply enough current or (if off) battery failure or
not charged.
3.1.3 DC-OUT-OK LED:
The DC-OUT-OK LED is a green colour LED that indicates the status of the output (lit for normal operation)
3.2 Remote ON/OFF:
The¨TSP-BCM12, TSP-BCM24(A) as well as TSP-BCM48(A) provides an external remote on/off function by use of pin 7
and pin 8 at connector J5 (see Fig. 2.1). To switch off the power supply and TSP-BCMxx(A) a connection between
Connector J5 pin 7 and Connector J5, pin 8 by use of a switch has to be made. At open connection between J5 pin 7 and
J5 pin 8 the device is providing the adjusted output voltage.
On the TSP-BCM12 TSP-BCM24(A) as well as theTSP-BCM48(A) a switch is available to switch off the system on site (in
the control cabinet).
Turning the system to OFF state (by switch or remote on/off function) during the battery discharge operation will fully switch
off the system and disconnect the battery. In this condition the system cannot be switched on again. If mains returns and the
system is still in OFF state, the battery will remain disconnected but a very low output voltage may appear (typically 2Vdc,
pulsing). Turning the system to ON state (by switch or remote on/off function) will bring the system back to full function
including battery charging and battery condition test.
3.3 Battery test (Jumper J4):
The TSP-BCM12, TSP-BCM24(A) as well as the TSP-BCM48(A) is designed to monitor the batteries condition. The
battery is loaded with a certain current pulse (the actual load) to monitor the batteries condition. The battery test pulse is
only present as long as the mains is present. The time between the current pulses can be set either to 15 seconds (see
Fig. 2.1, J4 Pin 1 & 2) or to 10 minutes (factory set) (see Fig. 2.1, J4 Pin 2 & 3).
3.4 Temperature sensing:
The TSP-BCM12. TSP-BCM24(A) as well as the TSP-BCM48(A) are designed to operate with temperature compensation
required for proper operation of the battery. The temperature is detected using an external NTC sensor (10k) connected
to the signal connector (J5 pin 9 & pin 10). If the sensor is not connected the device automatically switches to +25°C
constant temperature operation mode.
The factory setting for the battery voltage at +25°C ambient is: 2.28Vdc x 12 cells = 27.4 Vdc or 2.28Vdc x 24 cells =
54.8Vdc. No adjustment is required for the recommended battery. If different batteries are used, the output voltage must
be set accordingly by potentiometer as recommended for +25°C. The initial voltage should be adjusted only when the
battery and temperature sensor are disconnected. (Fig. 2.1).
The set voltage should be measured on J1 of the BCM (BATT-IN).
3.5 Setting the Max. Power Input on the TSP-BCM12, TSP-BCM24(A) or TSP-BCM48(A)
In order to adapt the TSP-BCM12, TSP-BCM24(A) or TSP-BCM48(A) module to the feeding TSP power supply the
maximum input power must be set in accordance with the maximum output power of the TSP Power supply. As the output
voltage of the power supply is approximately 14 Volts (TSP-BCM12) or 28 Volts (TSP-BCM24(A)) or 56Vdc (TSP-
BCM48(A)), the maximum allowed output current of the TSP power supply will be limited by the TSP-BCM module as per
jumper settings shown in the table below.
To ensure that the TSP Power Supply is not overloaded when used with the BCM modules, the jumper J6 needs to be
correctly set before commissioning the system. Incorrect settings for too high currents might damage the power feeding
supply.
Please refer to Fig. 2.1 & paragraph 2.3 for details.
