Operation
TCG 1xx control unit
The TCG 1xx control and safety unit
controls and monitors the forced draught
burner. The microprocessor-controlled
program sequence ensures highly
stable periods, regardless of fluctuations
in the power supply voltage or the
ambient temperature.
The control and safety unit is designed
to cope with brownouts. This system
protects the installation, even during
major voltage drops. Whenever the
supply voltage drops below its rated
minimum level, the control unit shuts
down - even in the absence of a
malfunction signal. The control unit
switches itself back on again once the
voltage has returned to normal levels.
Locking and unlocking
The control unit can be locked (switched
to malfunction mode) by pressing the
R
unlocking button, provided the unit is
connected to the mains power supply. If
the button is pressed during normal
operation or start-up, the unit enters
malfunction mode. If the button is
pressed in malfunction mode following a
safety shutdown,
the control unit is unlocked.
Always switch off the power supply
before installing or removing the
control unit. Do not attempt to
open or carry out repairs on the
control unit.
