Factory Reset
In the event of the password being lost or any other reason the user may require the unit to be
reset to the original factory settings, a "Factory Reset" that will clear all settings of the DEQ-230
and return the device to the original factory setting, is available to the user.
Note:
Continuing with this process will mean the DEQ-230 will re-initialize to the original factory
settings and any previously stored information and changed parameters will be permanently lost.
Use the following procedure to perform the factory reset:
1.
While the DEQ-230 is switched OFF, simultaneously press the ENTER+ESC+UTILITY
buttons on the front panel.
2.
Maintain pressure on all three buttons as you turn the power switch to On and the
following LCD screen appears on the DEQ-230:
3.
Release the buttons and wait for the DEQ-230 to re-initialize.
Once completed, the DEQ-230 will resume regular operation as though it was a new unit from the
factory and no previously programmed parameters will be available for use.
GND and USB/RS485 LIFT switches
The DEQ-230 on its back panel is providing a couple of switches allowing to connect or left
unconnected the power Supply Main GND and the USB'RS485 connectors GND to the chassis.
MAIN “LIFT/GND” Switch
- Actually can happen that sometime it is necessary to NOT connect
the Main Ground to the Chassis in order to avoid GND loops.
This is possible using the “MAIN” GND/LIFT switch.
When the switch is positioned on GND, the Main Power Supply GND is connected to the Chassis.
USB/RS485 “LIFT/GND” Switch
– When using a USB or RS485 remote control connection, can
be that the GND of the USB or RS485 cable it is not connected to the remote controller GND.
In this case it is necessary to provide it from the processor's side, and this can be done selecting
the GND position with the USB/RS485 switch.
On the other hand, if the GND of the USB/RS485 cable is already connected to the remote
controller GND, to connect the same ground also to the GND of the processor could create GND
loops or generate GND noises.
In this case, the switch on the position “Lift” will leave the cable GND not connected to the chassis
of the DEQ-230
