Dymax BlueWave® 200 Version 3.0 User Guide
Wiring the PLC Interface
The following information will allow you to connect any PLC to the BlueWave 200.
Input Signal Definition
NOTE: Asserting an input signal means connecting the input pin to +24VDC return. Approximately 12 mA will
flow out of the pin. The current is provided from the +24 VDC supply. A sample wiring diagram is given in
Figure 34 (Page 25). Un-asserting an input signal means removing the connection to +24VDC such that less
than 1 μA of current is drawn from the pin.
All input signals are ignored until the BlueWave 200 is placed in PLC Mode.
Table 1. Input Signals to the BlueWave 200
This is a power input to the BlueWave 200 and acts as a supply for input
signals. The supply should be regulated to 24 VDC +/- 10% and free of
noise.
This is the return to the power supply, and also the return for all output
signals.
When asserted, this signal will cause the shutter to open if:
1) The lightguide is fully inserted
2) The bulb is Ready
3) The BlueWave 200 is operating without faults
4) The remote shutter inhibit signal is not asserted
5) The PLC remote enable signal is asserted
6) The BlueWave 200 is in PLC Mode
7) The BlueWave 200 has power and the switch on the back is turned on.
When asserted, this signal will prevent the shutter from opening if:
1) The PLC remote enable signal is asserted
2) The BlueWave 200 is in PLC mode
When asserted and the following conditions are met, the bulb will turn
on and begin its warm-up cycle if:
1) The BlueWave 200 is operating without faults
2) The PLC remote enable signal is asserted
3) The BlueWave 200 is in PLC mode
When un-asserted, all other input signals are ignored and treated as un-
asserted.
NOTE: The LCD display will always show the actual state of all input
signals whether remote PLC enable is asserted or un-asserted.
