6.2.3. Binary Signal Inputs
The used binary inputs can differ from project to project. Please refer to the valid wiring diagram.
Designation
Description
Observation
Y1
Remote Close
Y2
Remote Open
Y3
Auxiliary Open & Hardware driven
safe Open
Can be used in all operating modes (Global, Local,…)
Input can be set as HW SAFE-Open. If failure of the WD READY
– signal, here the apparatus can be switched off independently of
the state and condition of the CPU
Y4
Standard Open or Protective trip
Input with extended voltage tolerance (see Table 4)
Y5
Selection:
-LOCAL/REMOTE
-LOCAL/GLOBAL
(Remote/Local
switchover function)
LOCAL mode: only the use of local push buttons is accepted,
except input Y3 which is always active.
REMOTE mode: only remote control signals are accepted
GLOBAL mode: all signals are accepted
Y6
Lock in Open
Locking of apparatus in the Open position
Y7
Under Voltage (
Under voltage
function)
Signal input for the detection of an undervoltage, variable voltage
values can be set

These represent the range of values the MABS card can accept. The specific voltage used still needs to be
selected via Dip switches as described later.
