4.2.- BASIC SETUP
Once the unit has been connected, it must be programmed in accordance with the installation's
features.
The following basic parameters can be programmed:
Adjust the trip current.
Adjust the trip delay time.
Select the frequency of the installation to be supervised.
5�- OPERATION
The
RGU-2
unit helps control the electrical insulation level of an installation by controlling the
intensity of the leakage current.

RGU-2
An external sensor detects and measures the earth leakage current.
Circutor
offers the follow-
ing unit protection models in its current range of sensors:
WG/WGS/WGC/TP-WG
.
When the instantaneous leakage current has been measured, the
RGU-2
unit will operate in
accordance with the programmed parameters:
- Trip current (
IΔn
)
- Trip delay time (
td
)
As a result, the status of the device's output contacts will be changed. The output of this contact
will be used as follows, depending on the final application type:
- Earth leakage protection (IEC61008-1), the circuit breakers are activated.
- Earth leakage monitoring (IEC62020), alarm alerts, sound and/or visual devices.
5.1.- KEYBOARD FUNCTIONS
The unit has 3 keys:
RESET
,
TEST
and
PROG
.
PROG
Key
Pressing this key displays the different screens and opens the programming mode (hold down
the key for 2 seconds) to adjust the different programming parameters.
This key is sealable; it is supplied with a small hole where the configuration can be physically
disabled.
