Enter the desired warning level from 1% to 100% then tap
SAVE
.
A value of 0% removes the warning from the selected channels.
Warning thresholds are set as a percentage and not the actual leakage current. This is
because of the manufacturing tolerances of
RCBO’s means that individual units might trip
anywhere between 20mA and 30mA of leakage. This can make it difficult to know when a
RCD is close to tripping so when the UNITOUR rack is manufactured, every RCD is tested to
determine its trip current and this value is stored and used to calculate the percentage of the
leakage current that will trip the RCD. The RCD will trip when the leakage reaches 100%. This
allows you to accurately see how close each channel is to its limit and to set an appropriate
alarm to warn you when the limit is approaching.

Tap to view either the
INPUT
LEVEL
or
OUTPUT LEVEL
of all channels. Output levels
might be different to input levels due to the effect of the switch thresholds of a switch or relay
channel or the curve of a dimmer channel.
Tap a channel to see detailed information about that channel. Channels can also be selected
by pressing their
CHANNEL SELECT
button located above each channel’s circuit breaker.
When a channel has been selected, the LED on the output module lights magenta and the
screen shows the detailed information for that channel.
