INTRODUCTION
Overfilling protection
The timer relay prevents the steam generator over-filling with feedwater
if the level control system stops working.
“Reset level
”
button
If a fault occurs on any of the safety components of the steam generator,
it must be reset manually in accordance with applicable boiler regula-
tions.
The button is also used when filling an empty steam generator with
water. See the Function check chapter in the INSTALLATION MAN-
UAL.
“Test level limiter” button
This button is provides a quick test of the operation of the boil-dry pro-
tection. The test interrupts the level circuit without the need to reduce
the water level.
RCD
Some types of steam generator must be connected to the electric power
supply via a residual current device (RCD). See the Installation instruc-
tions chapter in the INSTALLATION MANUAL.
Safety switch
It must be possible to isolate all electric power supplies to the steam
generator with a safety switch. The safety switch must be lockable in the
OFF position. See also chapter Installation in the INSTALLATION
MANUAL.
