Problem: The touch screen doesn’t turn on up after applying 115/230VAC.
Solution: Open the TRIO door and:
1. Check main 115/230VAC 3A fuse F2.
o
If required, replace fuse.
2. Check the 12V terminal voltage (COM & 12V).
o
If there is no voltage, there is a problem with the Switched Power Supply. Replace the
power supply.
3. Verify that the 5V and 3.3V indicative LEDs of the I/O power board are lit.
4. Verify that the flat cable connecting the I/O board and the display board is in place.
5. Verify that the Green Status LED is flashing.
6. On the TRIO display board, verify that the:
o
RED Status LED is flashing
o
Display’s flat cable is firmly hooked up to its connector.
Problem: The screen doesn’t reflect changes made in the analog inputs
.
Solution:
1. Verify that the position of Dip Switch (S1-S6) corresponds with the relevant analog input.
2. Verify that the analog input terminals’ mapping corresponds to the actual wiring.
3. Check that the terminal wire connection of Analog Input of interest coincides with the analog
input chosen on the touch screen.
Problem: The screen doesn’t reflect the changes in digital inputs.
Solution: Verify that the digital input terminals’ mapping corresponds to the actual wiring.
Problem: The Alarm Relay doesn’t operate.
Solution: Check fuse F4.
o
By default, alarm relay contacts “NO-COM” should be closed.
Problem: The analog output voltage doesn’t correspond to the voltage defined on the corresponding
analog output terminal.
Solution: Check the load value. The maximum analog output load is 15 mA.
Problem: An analog output terminal has no output voltage.
Solution: Verify that the analog output terminals’ mapping corresponds to the actual wiring.
Problem: The display screen appears but does not respond to any touch.
