it will increment the second digit of the Set Display. The same will happen with the up key (3) and the third digit of
the Set Display, and up key (4) and the fourth digit of the Set Display. The Timer will increment from 9 back to 0.
If the timer is not operating, the Timer should periodically update the present value with the set value; if Timer
does not, press the Reset Button. Reset value will become the present value. The Timer comes programmed for
a range of 00.01 seconds to 99.99 seconds. Consult the factory for other time ranges and functions.
UTILIZING A DYMAX FOOTSWITCH TO OPERATE THE BLUEWAVE
®
50’S WITH A PLC
1. The Footswitch Receptacle located on the rear of the unit can be used to control the operation of the Shutter
with a PLC.
2. The simplest way is to disconnect the Footswitch from the Cable. This frees up the Cable for use with a PLC.
3. To use a PLC, computer, or similar control device with the
BlueWave
50, the Control Device must be isolated.
Isolation can be achieved with use of a R
elay. Most PLC’s provide Relay outputs. Wire the Control Device to
operate the Coils of the Relay. The R
elay’s Contacts must be rated to handle 12V 1A.
4. To open the Shutter turn on Q1, Q2, K1, or close S1 or S2.
5. As long as the Safety Contacts are closed (Q3 and Q4 turned on, K2 energized and S3 and S4 closed) the
Shutter will open. Opening any Safety Contact will block Shutter activation but will not close the Shutter in
“Timed” operation, only in “manual” operation.
