46 F300S/F300SQ Ultraviolet Lamp System
NOTE: A dry contact (such as a relay contact or a PLC containing a relay
contact) with gold contact material should be used to drive the remote inputs.
The cable length to the dry contact should be no more than 6 meters. Shielded
cable should be used to minimize possible electrical interference.
In a multi-lamp system, connections are made to the Master power supply.
If there is a requirement for clearing faults remotely, a Remote Reset switch must
be used.
Output Ports (J105B)
There are five relay outputs available on the P300M/P300MQ/P300MT through
J105B. These outputs may be used to synchronize customer equipment with the
system. In a multi-lamp system, connections are made to the Master power supply.
