RELAY DE-ACTIVATION PROCEDURE FOR GS3-500 UNITS
CAUTION
DO NOT WORK ON PANEL WITH POWER APPLIED!
1. Disconnect all power sources from GS3-500 unit.
2. Locate 4 screws securing the top cover and remove cover.
3. Locate relay activation switch on the rear of the control panel as shown in Figure 2.
4. Flip the Relay Activation Switch to the
“OFF” position as indicated in Figure3.
5. Reinstall top cover using the 4 screws removed in step 2.
6. Apply incoming power to the unit by connecting the power cord to an approved receptacle. Make sure the
blower is not running and the green power light is off. This is called the
“Soft On” state.
7. Now that the physical switch is activated and the unit is in the
“Soft On” state, the software will need to be
reprogramed via a flash drive with a configuration file and the USB port on the control board. (Contact Fumex to
acquire the correct configuration file for your unit).
8. Reprogram the software by changing the
“remoteSwitchOnly” setting in the configuration file to “0”. This will
unlock the Control Board power button. The ON/OFF function will only be able to be controlled by the front panel
on the unit.
9. After changing and saving the configuration file, plug the flash drive into the USB port on the front of the
control board. (Make sure the unit is in the
“Soft On” state before plugging in the flash drive.)
10. After the reprogramming is complete the light above the USB port will turn green and remain lit until the flash
drive is removed from the USB port.
11. Remove the flash drive and start the unit as described in the
“Controls” section.
Once the relay activation switch is turned off and the configuration file
has been reprogrammed the unit will only start by using the front
control panel. All relays will become non-functional.
