The control circuit terminals are common for all sizes H1 … H8.
Location of the control circuit board SDCS-CON-H01
The SDCS-CON-H01 is mounted on an electronic tray. The electronic tray is attached in the housing by means
of two hinges.
Watchdog function
The SDCS-CON-H01 has an internal watchdog. The watchdog controls the proper function of the SDCS-CONH01 and the firmware. If the watchdog trips, it has the following effects:
– the thyristor firing control is reset and disabled
– all DI’s will not be processed
– all DO’s are frozen in the actual state
– all AI’s will not be processed
– all programmable AO’s are frozen in the actual stateArmature circuit interface
The function for the armature circuit interface consist of:
– Firing the armature bridge of 6 or 12 thyristors.
– High ohmic measurement of DC and AC voltages.
– Residual measurement current of armature circuit to ground
= 5 mA at 500 V supply ( 1 M).
– Interface for the current transformers for current measurement.
– Snubber circuit for the thyristor protection together with R1 on the heatsink.
– Interface for heatsink temperature measurement with a PTC.
– Fuses for overvoltage protection and field circuit.

Following connectors are available:

  1. Four identical channels for current measurement on the mains side via CTs connected to X231 / X232, X241 / X242,

X251 / X252 and X261 / X262.

The AC current is rectified by diodes on the measurement board.

The burden resistor is automatically scaled by the type code setting in the firmware for CT ratios of either 1:2500 or

1:4000.

  1. AC voltage and motor voltage are measured by four different types of inputs.

20 VAC … 100 VAC: Voltage measurement via X15. For this remove the zero Ohm resistors R221 … R225.

This results in 1.2 MOhm inputs.

100 VAC … 525 VAC: Voltage measurement via XU2, XV2, XW2, XC2 and XD2 (about 1 MOhm to ground).

526 VAC … 1000 VAC: Voltage measurement via XU1, XV1, XW1, XC1 and XD1 (about 2 MOhm to ground).

100 VAC … 1200 VAC: Galvanically isolated voltage measurement via X15. For this DC-DC transductor A92 and

transformer T90 have to be used. X15 provides 27.4 kOhm inputs.

  1. X22 is used for DCS880 NTC temperature sensor.
  2. XC12 connection to SDCS-CON-H01 (size H6) or SDCS-OPL-H01 (size H7, H8)
