Compliance with Standards
ICAO: Aerodrome Design Manual Part 5, para. 3.2.1.3
Uses
To supply up to eight series circuits from one MCR3 constant current
regulator: either alternately (only one series circuit switched on at the same
time) or simultaneously (different series circuits switched on at the same
Fig. 2
time).
Typical applications:
- Simultaneous supply of several taxiway tracks by one MCR3 and one
CSR (Fig.3).
- Alternate supply of PAPI’s and/or approach systems located at both ends
of a runway (Fig.4).
Features
• Modular concept: only two sizes of cabinets, two types of contactors and
two PCB’s cover all versions.
• CSR and MCR3 operate as one unit.
• Can be wall mounted or - optionally - incorporated into the MCR3
enclosure.
• Easy series cable termination with integrated traction release and
provision for cable screen earthing.
• Readily exchangeable PCB’s with plug-in connectors.
• Fully lamp safe due to zero current switch over in case of load reduction.
• Available for 2 up to 8 circuits.

Concept
Remote or local operation modes are activated by the MCR3.
High-voltage contactor interlock controlled by a microcontroller on
the logic board. The MCR3 switches on after at least one circuit has

been selected. If no circuit is selected, the MCR3 switches off.

Simultaneous operation:
When additional circuits are selected, the current drop is

The output current drops down to zero and rises again to the
selected level in case of de-selection of circuits.
Alternate operation:
Taxiways
The output current drops down to zero and rises again to the

selected level after another circuit is selected.
Technical Data
Series circuit current: 6.6 A or 20 A.
Max RMS output voltage of series circuit:
- MID range: 1515 V AC (only 6.6 A) (Fig.1)
Fig. 4
- HIGH range: 5000 V AC. (Fig.5)
Auxiliary power supply:
220, 230, 240 or 400V AC (50 or 60 Hz).
Remote control and monitoring via MCR3:
- Multiwire: 24 V or 48 V DC.
- BUS:RS485 standard, point-to-point connection with MCR .

Standard Options
Remote control and monitoring
The CSR offers the following choices:
Fig. 5
Multiwire remote control with two voltage ranges:
24 or 48 V DC.
This version provides full remote control and back indications;
e.g. selection of circuits, shut-down, remote or local operation, ...
BUS remote control: A microcontroller in the MCR3, using a fieldbus with
hardware according to RS485, allows the remote monitoring of a larger
quantity of parameters (e.g. all dip switch settings).
Hour counters: available via MCR3 HMI
The hour counter of each circuit has following properties:
- Resettable to 0.
- Presettable: an alarm is created when a user-adjustable pre-set time
is reached.
- Output current dependent: the counter starts when a useradjustable
output current level is reached.
Incorporated in MCR3 (on request)
The MID range CSR may be incorporated in the MCR3 enclosure.
(Max. 6.6 A / 1515 V, up to 10 kVA). In this case, a special execution of
the MCR3 has to be ordered.

The circuit selector shall be designed for the alternate supply of two series
circuits or the simultaneous supply of up to eight series circuits from
one constant current regulator.The working voltage and current breaking
capacity shall suit the characteristics of the constant current regulator
associated with the circuit selector. The circuit selector shall be controlled
from the CCR. It shall be provided with electrical interlocks to prevent undue
simultaneous switching of series circuits circuits and to de-energise the
regulator when no series circuit is selected. The switching of series circuits
shall not cause over current in the other series circuits. It shall be possible
to display all status values on an alphanumerical display on the front door of
the circuit selector. The circuit selector shall be housed in a self contained,
metal sheet enclosure, suitable for wall mounting or shall be incorporated in
the constant current regulator. The remote control and monitoring system
shall be available from the CCR as either a 24V or 48V DC multiwire version
or a RS485 hardware BUS version.
