More Information

Overview Manuals Current Matching Circuit Layout Connector Routing Adjustment Boundary

Features:

  • Serves as the field board for SIMOREG units built with disk-type thyristors.
  • Pairs two Type D armature ranges with their documented field-current classes.
  • Routes the board connection through X102 and four named field terminals.
C98043-A7004-L1 is selected as an electrical configuration, not by the A7004 family name alone.

Its V7/V8 thyristor positions and the eight 0R04 resistors define the field-board circuit arrangement.

The wiring references separate the board-to-board path from the external field conductors used by the converter.

The Siemens C98043-A7004-L1 Field Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Converter Current Pairing

  • Converter form: C98043-A7004-L1 is assigned to the Type D arrangement.
  • Lower armature class: The 900–1200 A range is paired with a 30 A field.
  • Upper armature class: The 1500–2000 A range is paired with a 40 A field.
  • Selection boundary: Armature and field values must be checked as one documented pair.

Field-Circuit Hardware

  • Thyristor positions: The field circuit identifies devices V7 and V8.
  • Resistance set: R1 through R8 are each marked 0R04.
  • Board group: The circuit belongs to the A7004-L1/-L2 hardware grouping.
  • Configuration check: Device positions and resistor values jointly identify the arrangement.

Connection References

  • Internal link: X102 connects with the matching A7002-X102 point.
  • Supply terminals: The AC-side field references are 3U1 and 3W1.
  • DC field points: Terminals 3D and 3C complete the named field path.
  • Lead separation: Betatherm and gating conductors retain their specified cross-sections.

Post-Replacement Control Step

  • Required function: P051=22 initiates the internal offset adjustment.
  • Trigger condition: The step follows replacement of the C98043-A7004 field board.
  • Power state: Hardware work is performed with the converter de-energized.
  • Personnel limit: The procedure is reserved for qualified service personnel.
Description
Within SIMOREG DC-MASTER converter hardware, Siemens C98043-A7004-L1 is the field board assigned to units that use disk-type thyristors. It belongs to the A7004-L1/-L2 board group and carries the field-circuit hardware for the specified Type D converter arrangements.

Two current pairings define the documented scope of C98043-A7004-L1: 900–1200 A armature current with a 30 A field, and 1500–2000 A armature current with a 40 A field. The board implements the V7 and V8 thyristor positions together with resistors R1 through R8, each identified as 0R04, so the current class and the resistor network form one configuration boundary.

Connection routing on C98043-A7004-L1 links X102 to A7002-X102 and uses field terminals 3U1, 3W1, 3D and 3C. The Betatherm 145 conductors are specified at 6 mm² and the gating leads at 1 mm²; after a field-board replacement, the internal offset adjustment is repeated through function P051=22.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can a technician distinguish C98043-A7004-L1 from another A7004 board before removal?
Check the complete C98043-A7004-L1 marking, then compare the Type D current pairing and the R1–R8 0R04 resistor network.
Which connection labels should be recorded when documenting a C98043-A7004-L1 installation?
Record X102 and its A7002-X102 destination together with field terminals 3U1, 3W1, 3D and 3C for C98043-A7004-L1.
Why does a C98043-A7004-L1 board change require an offset step?
The documented field-board procedure calls for internal offset adjustment through P051=22 after C98043-A7004-L1 is replaced.
A drive is rated at 1500–2000 A armature current. Which C98043-A7004-L1 field class belongs with it?
For that Type D armature range, C98043-A7004-L1 is paired with the 40 A field configuration.
Can the two documented conductor sizes on C98043-A7004-L1 be interchanged?
No. C98043-A7004-L1 assigns 6 mm² to the Betatherm 145 conductors and 1 mm² to the gating leads.
What safety boundary applies before working on C98043-A7004-L1?
C98043-A7004-L1 must be handled with the converter de-energized and by qualified personnel under the field-board procedure.
