3 Basic Tests
Once the wiring is completed, the Hydro-Control can be switched on by pressing the power button
in the top right corner marked with the symbol .
The unit will run through a self test and boot up the Hydro-Control. A splash screen will be
displayed followed by the software version number before displaying the main screen.
After successfully starting up the system, it is recommended to commission the system by first
testing the sensor communications and I/O using the following instructions. This should be done
before setting up the system parameters.
3.1
Sensor testing
The Hydro-Control uses an RS485 serial interface to communicate with the Hydronix moisture
sensor in the mixer. Once the unit has finished loading it will display the main screen with a
banner across the centre reading ‘Searching for Sensor on address xx’ showing the address of
the sensor being requested at that time.
During this time the Alarm output is set to signify a problem to the control system.
Once the unit has searched all the RS485 addresses, it should find the sensor and display the
reading from it in the trend display.
Run through the following procedure to test that the sensor is functioning properly:
1. Press the Display Unscaled button . This displays the incoming sensor
value in terms of the unscaled units (0 in air, 100 in water). This is not a moisture %
reading and allows the basic sensor value to be seen.
2. Whilst the mixer is empty (with the sensor in air), the sensor value should read between
0 and 15 (this number will vary depending on differences in the installation).
3. Place a wet cloth over the sensor’s ceramic faceplate. The sensor value should rise up
to between 70 and 90 (this number will also vary depending on how wet the cloth is and
the speed of the signal change will depend on the filtering settings in the sensor). This
test can also be done by placing a hand over the sensor’s ceramic face.
If these tests are completed correctly, then you can be certain that the sensor installation and
communications with the Hydro-Control are working. Press Display Moisture to
switch back to moisture mode.
3.2
Testing the I/O
The I/O Setup And Status screens may be selected by pressing the Menu button and
then pressing the I/O Setup And Status button .
This will display the first I/O Setup And Status page shown in Figure 19, which can be used to
test the Digital Inputs and Outputs.
