Issue
When using the ribbon cable provided with Satchwell MicroNet Touchscreens or LCDs to supply power from a MicroNet 50 series controller powered by 24VDC, the display units may not function correctly due to hardware incompatibility.
Product Line
Satchwell MicroNet
Environment
- Satchwell MicroNet Touchscreens
- Satchwell MicroNet LCDs
- Satchwell MicroNet 50 series controllers
Warning
Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source.
Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices.
Cause
- The MicroNet 50 Series controllers support both 24VAC and 24VDC input.
- The Touchscreen and LCD displays are adapted from MicroNet 100 Series hardware, which does not support 24VDC power input.
- Using the ribbon cable to supply 24VDC from the controller to the display can result in malfunction or damage.
