6.8.4.7 Anti-Two Block input
Refer to DIO connection drawing in the rear of the manual.
Provision has been made on the board for the direct activation of Output 1 via an external
switch.
This produces an instantaneous output signal, avoiding the possibility of delays caused by
software.
To use this facility, ensure that link P4 is in the “ON” position that allows the CPU to read the
status of the switch. The user then has the choice of allowing the CPU to over-ride the
condition (ie in Rigging mode) or to leave total control to the external switch. If CPU control
is desired, then link P3 must be in the “ON” position, otherwise leave it “OFF”.
If control has been given to the CPU, then the user must ensure that the fault status switch for
Output 1 is in the “OFF” position, otherwise in a fault condition the output will be over-
ridden. Once this has been set up, the status of the output is defined by the status of the
external switch connected as per the wiring detail, with the output relay being energised (ie
closed contacts) when the external switch is closed.
6.8.4.8 Slewing Zone Switch/es input/s
Fit slewing zone indicator micro-switch (or proximity switch) provided at a convenient place
near the centre of rotation providing run on and off ramps as required for the particular
application. This switch will convey a signal to the Control Unit when the crane moves into a
zone of restricted capacity rating. For correct wiring instruction refer to drawings at the back
of this manual.
The switch wiring requires a "voltage free"
connection. Never connect the switch wiring into
any other system/wiring loom unless the exact
nature of the connection is known.
6.8.4.9 Motion Cut
If motion cut is required the client shall provide appropriate solenoid valves/devices to
activate the function and wire them as shown in this manual.
