If the alarm does not occur due to wrong wiring, it is necessary to
substitute the logic. The failure could be in a mechanical relay defect
or in a fault of the relay driver.
10) KS CLOSED
Cause:
It occurs when the MM has detected the SM safety contact closed
before it's commanded.
Remedy:
The alarm can be due to a wrong installation. As figure 11.1.1.1
shows two cascaded safety switches are internally connected. They
have three diagnostic points; low voltage, mid point and high voltage
end that are read by software. When the switches are open, the
three diagnostic points expect to be at different potential values
thank to the resistances. If the outside interface connected on pin #1
and pin #7 of connector CNB gets one end equal to the midpoint, it
looks like the switch is closed before it is driven and this unwanted
alarm occurs. So we recommend the safety switch should be directly
connected to the supply source (plus battery or minus battery) with
no interposed switches.
If the alarm does not occur for the wrong wiring, it is necessary a
logic substition. The failure could be in a mechanical relay defect or
in a fault of the relay driver.
11) KM OPEN
Cause:
It occurs when the MM has detected its safety contact open after
being commanded.
Remedy:
If the alarm occurs permanently, it is necessary to substitute the
logic. The failure could be in a mechanical relay defect or in a fault of
the relay driver.
12) KS OPEN
Cause:

after being commanded.
Remedy:

logic. The failure could be in a mechanical relay defect or in a fault of
the relay driver.
13) DATA ACQUISITION
Cause:
This alarm only occurs when the operator turns to level 1 the
"Adjustment #1"
Remedy:
switching off and on the key will automatically remove the alarm.
