The global success of TSC modules is a result of the simplification of all vital electronics for
the AC and DC functions of the system to a single circuit board.
All modules of each type are interchangeable and identical for rapid replacement. The
modules are hard-wired to eliminate loose connections caused by vibration. Each module
is subject to rigorous testing to eliminate any defective components. Modules are calibrated
at the factory and require no adjustments in the field. Service and troubleshooting of the
system is minimized.

AC Control Module
The AC module consists of the electronics for automatic control of the
engine generator set:
Electronic engine governor
Electronic generator voltage regulator
Automatic load sharing circuit for parallel operation
Reverse power, under frequency, over-frequency, pulse loss and over-
voltage protection
DC Control Module
The DC module consists of the electronics for automatic control of the SCR
converter:
Automatic load sharing system for the drawworks, rotary table and mud pump motors
SCR firing circuits with ‘hard firing pulse’ output
Gate suppression at approximately 150% of the highest single motor current limit
All controls are designed to be ‘fool-proof’
Individual control of current limits for all drilling functions
Zero throttle interlock
