Digital controller RK 4004
In normal circumstances the display on the controller card indicates
only three dots. These three dots signal that no errors are present .
A flashing number signals an error. The number indicates the error
code. If several errors are present at the same time, the error with the
highest priority will be indicated. If this error is no longer present, the
display will indicate the next error.
Below is a list of possible errors:

4.2.3 Output X 20.4
In the case of certain errors (see table) output X 20.4 is switched to
"0". The internal switch on the controller card that furnishes a con-
nection to ground is opened.
The following circuit variants are recommended:
Lamp "ON"
=
system on stand-by
Lamp "OFF" =
error
PLC "1" =
system on stand-by
PLC "0" =
error
