CAUTION: DO NOT megger or high-pot the generator with the regulator connected. DO NOT high-pot the regulator.
FUSE
A 4 Amp, 250 V, 5 x 20 mm fuse is supplied with the regulator.
It can be located on the rear face of the voltage regulator.
EXCITER POWER CIRCUIT
Connect the regulator wire F+ to the generator F+ or Fl field terminal. Connect the regulator wire F- to the generator F- or F2 field terminal. See Figure for typical connection diagram
SENSING/POWER INPUT CIRCUIT
Input power and sensing is achieved through terminals 3 and 4. The voltage input requirement of the SE350 is 190 to 240 Vac. See Figure.
VOLTAGE ADJUST
The screwdriver adjustable potentiometer adjusts the generator output voltage. Adjustment clockwise increases the generator output voltage.
When using a remote voltage adjust rheostat, remove the jumper wire across terminals 6 and 7and install a 2000 ohm
1/2 watt (minimum) rheostat. This will give ±10% voltage variation fromthe nominal. (For ±5% voltage variation use a
1000 ohm 1/2 watt rheostat). See Figure.
STABILITY ADJUST
System stability is the ability of the generator to respond to load transients. Decreasing the stability makes the generator
less sluggish and faster to respond to toad transients. If the stability of the regulator is decreased too much, the generator
will tend to hunt under steady state conditions. The screwdriver adjustable potentiometer adjusts the system stability.
Adjustment clockwise increases the stability. Increasing the stability increases the response time of the generator.
Conversely, decreasing the stability decreases the response time of the generator.
V/HZ ROLL-OFF FREQUENCY SELECTION
The roll off point is the frequency where the generator voltage starts to decrease. This reduces the Kilowatt load to the
engine, which allows the engine to recover in speed under any load transient condition. Use jumper to select 50 HZ or
60 Hz. The screwdriver adjustable potentiometer sets the roll-off frequency from 54-61 Hz in the 60 Hz setting or from
45-51 Hz inthe 50 Hz setting.
The SE350 has the roll-off point preset to 58 Hz in the 60 Hz mode and 48 Hz in the 50 Hz mode. To change the roll-
off point, adjust engine speed to the desired rated speed. (50 or 60 Hz).Set the voltage to the desired setting at rated
speed. Adjust engine speed to the desired roll-offpoint. Turn the potentiometer counterclockwise until the voltage starts to drop off. Then adjust the potentiometer clockwise until the voltage returns to rated
voltage. Re-adjust engine speed to rated speed.
