Partial power–up sequence
Open generator mains supply
switch S1 ("0" position).
On 200PL1, disconnect XJ4,
XJ6, and XJ7.
200PL1: Configuration the
of IN2 voltage selection
"strap" correct? (see
)
On 200PL1, unscrew and
disconnect one end of R1 or R4.
Measure values of R1 and R4.
200PL1 R1 and R4
values correct?
Yes
200PL1: Connectivity
between R1 and R4
and surrounding
circuits OK?
Yes
Yes
On 200PL1, check continuity between
XJ7 and terminal 4 of relay X1, and
between XJ3 and terminal 7 of relay X1.
Continuity checks
OK?
Yes
On 200PL1,measure resistance between terminal 4 of relay
X1, and 0 V. The resistance must be approximately equal to
R1 and R4 in
series
if strap IN2 is in position "HT" or R1 and
R4 in
parallel
if strap IN2 is in position "BT". See
and
A007 - Line Resistance Measurement
