Reverting to Factory Settings
GMW90 series transmitters, including factory-customized transmitters,
can be reverted to their original shipping configuration using the DIP
switches or the service port.
Reverting the transmitter to factory settings clears all user configuration
that has been done using the service port. User-made adjustments are also
cleared from the GM10 and HTM10 measurement modules. The factory
calibration will remain.
Reverting to Factory Settings Using DIP
Switches
1. Disconnect the transmitter cover from the mounting base.
2. Make a note of the DIP switch positions before changing anything,
so you can restore the positions later.
3. Analog output models: Set the DIP switches as shown in Figure 30
below: move all switches up.
Digital output models: Set the DIP switches in the leftmost DIP
switch bank as shown in Figure 31 below. Do not move the
switches in the other bank.
