Initial Setup and Commissioning
1.
Install the regulator and SE350 module and wire up to the correct wiring diagram
(Connection A, B, C, or D).
2.
If installing the SE350 on a brush-type generator, verify that the brushes and brush
riggings are isolated, ungrounded, and connected ONLY to the SE350.
3.
Turn the internal voltage control on the voltage regulator 15 or more turns counter
clockwise (left) or until you hear the screw click. This procedure is necessary in case the
original factory settings have been altered.
4.
If you are using a remote voltage adjustment, set it at 50% of adjustment.
5.
If the generator is to be paralleled, set the droop resistor between 6
Ω
and 10
Ω
.
6.
Start up the prime mover and bring up to operating speed and turn on the regulator
switch (if used).
7.
Set the internal voltage adjustment on the voltage regulator to the desired voltage setting
for the generator output by turning the adjustment screw clockwise (right).
Note that the voltage adjustment is a 25-turn pot!
8.
Place the generator on line and observe the frequency and voltage.
9.
If the generator is being paralleled, measure the droop during loading and adjust the
droop resistor as necessary. Reducing droop resistor resistance will reduce droop.
NOTE:
Loading the generator with a purely resistive load-bank may cause
undesirable droop characteristics such as no droop, very slight droop, or even
rising terminal voltage. Measure droop with a mixed load for best results.
10.
If paralleling and the terminal voltage rises or excessive amperage exportation occurs
during loading with a mixed load connected, reverse the CT leads and try again.
11.
Observe voltage regulation during no-load and full-load conditions. Once the voltage is
set and regulating characteristics are satisfactory the installation procedure is complete.
