Table 4-5 Startup Procedures for Remotely Operated Units
Step Single Unit and Units Networked to a Master Unit Operated Remotely
1 Switch the electrical disconnect enclosure to ON.
2 Turn the main power switch on the front of the power supply unit to the on position. The
power on message begins to scroll.
The power on message begins with the words UV CURING. Three numbers will then scroll
listing the software versions for the display board, main control board, and the phase board
respectively.
3 Make sure that all interlocked access doors are closed and that the exhaust fan is running.
If external interlocks are wired and open, a fault message F LOCK will appear in the display.
4 On the NETWORK selector, press Remote.
NOTE: For networked units, press Remote at each NETWORK selector.
5 Set the POWER SETTING. There are two ways of setting the POWER SETTING.
If the power level will be set at the control panel prior to turning on and off remotely (Remote
Operation), select the desired power level and save it while the unit is in Local mode. At the
Network Selector then select Remote.
6 Enable the cooling fan by either an external/remote switch or a set of contacts from the
power supply. If the exhaust fan is wired to the normally open set of contacts on the power
supply they will close when the lamphead is put in STDBY or LAMPON mode. If there is
insufficient pressure (less than than 7 in. H
2
O static pressure) there will be a system fault
and the message F PRSW will appear in the display. (Check for proper pressure with the
appropriate instrumentation.)
7 There are many ways that the system can be configured to operate Remotely. By utilizing
the power supply I/O the UV system can be controlled from a simple panel or fully
automated to work in concert with a complete process. Contact a Nordson UV Curing
representative for details.
