Start-up-, Service- and Operation Manual hotcontrol cDT+
Rev. 1.00.05
Subject to technical changes
13.7 Residual current RC
13.8 Current alarm Cur
RC
The residual current (see parameter
sidual current) set was exceeded for
hotcontrol cDT+
and
the Heatings were de-energized (relay on HTC-Card OFF).
How it works
The residual current for the hot runner controller is mea-
sured by the current transformer in the feed line of
hotcon-
trol cDT+
and registered in the CUI07.
What good is it
The residual current provides the user with a specific indica-
tion of the error in the hot runner or of a wrong setting, and
provides the ability to pinpoint errors quickly and correct it.
Remedy
Reason
Trouble Shooting
Tool humid
Check tool on humidity
Due to poor / wet insulation, a part of the current flows e.g.
via the protective conductor or directly in the ground.
Limit value wrong
Check settings for limit value and adjust it, if necessary
Cur
On the Heating output a short circuit was detected.
How it works
At switch-on of the zone the heating current is controlled. Is
a defined limit exceeded, there may be a short-circuit. The
Heating circuit is de-energized (relay on HTC-Card OFF).
What good is it
A current alarm with subsequent disconnection avoids dam-
age on the device and provides the user with a specific in-
dication of the error in the hot runner.
