Features of the System Power Supply
Power Supply Plans
Three (functionally equivalent) pairs of terminals (EXT, INT, BAT) are provided on the MIB module
card for supplying power to the system and the sensors. All of the system cards and the sensors
can be supplied from each of these connections. A voltage changeover switch is provided on each
system card, which ensures that only one of the voltages being applied is actually accepted. Var-
ious power supply plans are available to suit the number and type of sensors and/or the required
degree of redundancy in the power supply.
If the internal rack power supply unit is not sufficient to power all the sensors, an external unit must
be provided. The internal unit must then be disconnected. A redundant power supply is then pro-
vided by external units via the BAT or INT terminals.
Supply Plan A: Internal Power Supply Unit
All of the units of the system and the sensors are supplied by the rack power supply unit (INT ter-
minals). This variant is used when no power supply redundancy is required and the power which
can be supplied by the unit installed in the rack (150 W) is sufficient to supply all of the rack mod-
ules and the connected sensors.
Supply Plan B: External Power Supply Unit
All modules of the system housed in the rack and the sensors are supplied by the external power
supply unit (EXT terminals). This variant is used when no redundancy is required in the power sup-
ply and the power of the unit installed in the rack (150 W) is not sufficient to supply all of the system
modules and the connected sensors. A maximum of 20 A can be supplied across the terminals
(480 W system power).
Supply Plan C: Internal Power Supply Unit + Battery
•
The customer is responsible for providing a safety cut-out (maximum rack power, 480 W/
20 A).
•
The 85 ... 256 VAC is supplied via screw terminals directly on the power supply unit.
•
The system is supplied with an operating voltage of 24 VDC (19.2 ... 32 VDC).
•
3 pairs of terminals for the connection of three 24 VDC power supply sources (EXT, INT,
BAT) are provided on the Interconnection Board (MIB module).
•
The EXT, INT and BAT voltages are supplied to each system module.
•
If all three voltages (EXT, INT and BAT) are being supplied, only one of them is allowed
through to supply the module. The prioritisation of this connection is as follows:
1st = EXT, 2nd = INT, 3rd = BAT. Example: If the EXT, INT and BAT voltages are all present,
it is the EXT voltage that is passed through.
•
The voltages required for the individual modules are obtained in the modules themselves
from the 24 V.
•
The power requirement that must be met is derived from the type and number of sensors
connected and from the components installed in the system.
•
The maximum power provided for one rack is 480 W (maximum current of 20 A).
•
The MDA module measures all the input voltages and can generate error messages, which
can be shown on the display unit. In addition, a POWER FAIL relay is de-energised when
the status of the system power supply changes.
