Thermal Relay
5.2.7.4 Thermal Relay
This relay sends the signal to the 3-Phase circuit breaker and the
1-Phase breaker to trip-off when over-current flows in the circuits.
When the breaker trips-off, it is set at the middle of ON and OFF. In the
case, please recover the breaker, according to the following procedure;
①
Stop the engine.
②
Open the control panel and push the reset button of the
thermal relay.
You can recover the breaker to the ON position.
<Caution>
Do not change the preset value of the thermal relay.
5.2.7.5 Earth Leakage Relay Unit
Sensing the earth leakage current, the unit (relay) send a signal To the
3-phase and the 1-phase breaker to trip-off in order to shut-off The circuit
to the terminals (loads).
(refer to.
7-3 Earth Leakage Relay Unit and Grounding
)
5.2.7.6 Amp Meter Changeover Switch
Using this switch, the current between the phases (R.S.T) will be
displayed on the Amp meter.
5.2.8 Voltage Regulator and Throttle Lever
5.2.8.1 Voltage Regulator
The dial adjusts output voltage.
By turning the dial clockwise, an operator can increase the voltage.
By turning the dial counter-clockwise, an operator can decrease the
voltage.
