Dual Phase+ Power Supply
5100636 Rev. F
The Dual Phase+ indicates a fault condition with a flashing red light. The flashing
red light indicates that a hard arc has been detected by the system. For safety the
high voltage generators of the Dual Phase+ are shut down under this condition.
To correct this condition it is required to inspect the connected Conveyostat for
wiring faults or other short circuit conditions in the high voltage wiring. The fault
condition can be cleared by cycling power or depressing the reset button on the
front of the unit.
Remote Interface
Figure 4. Remote Interface Pinouts
The Dual Phase+ includes a 12 position connector that allows the user to remotely
interface to the unit. The remote interface provides relay contacts reflecting the
conditions of power, warning and fault. The remote interface also has an on/off
input allowing the unit to be switched on/off remotely.
The remote on/ off input of the Dual Phase+ requires on 24 VDC. Application of 24
VDC to the remote on/off pins of the interface turns the unit on. Note that cycling
power to the unit through this interface can also be used to reset a fault condition.
To use the remote on/off feature the front panel switch of the unit must be in the
off position.
The Power state of the Dual Phase+ is indicated on Power Relay pins of the remote
interface. When the unit is powered the state of the power relay changes and it is
held in this state. This allows detection of AC power loss to the Dual Phase+, as well
as an off condition.
