1.1 DESCRIPTION
The
rgf300
series three-phase cutting regulators comprises two electronic cards on a vetronite support
mounted inside the
GEWISS
IP55
GW Plast
120°C
case.
The two cards represent the
control
section (upper) and
power
section (lower).
fig. 4
The
control card
contains the following regulation, connection and signalling components:
•
trimmers
Marked
"

working points
on the transducer skale (only with
PB 1064
option)
•
relay
