Power Switch
When the Power switch is set to the Standby position, dangerous voltage is still present in
the controller's internal power supply circuitry. To ensure safe working during maintenance,
the controller must be isolated from the ac and dc input supplies.
A two-way rocker switch is used to connect (On position) and disconnect (Standby position) the internal
power supplies to the controller's circuits.
ac Input Connector
A chassis mounted 3-pin plug for the ac input supply (see Fig 3-2 ). This plug has an integral fuse. The
values of the ac fuses are shown below. Note that the fuses are safety critical items (see page 6-2 ).
For 110 to 120 Vac range, 20 mm, 125 mA anti-surge, Park Air part number 29F01490102S.
For 220 to 240 Vac range, 20 mm, 63 mA anti-surge, Park Air part number 29F01480102S.
