The function of the switch inputs is defined in software and reference should be made to
the software configuration sheets for details.
5.8.4.3.
Outputs
All eight outputs consist of normally open voltage free contacts that close when the output
is on. Each output is isolated from all others. Hence to have an output switch high one side
must be tied to the supply and the other is used to drive the load. The opposite applies for
switch low output. Since all outputs a fully isolated from each other this allows some
outputs to switch high and others to switch low.
Note: These outputs are not fuse protected through the
RCI-1550, hence the protection must be provided by
external means.
5.8.4.4.
Snubber diode protection to crane fitted solenoids or relays
The use of snubbed inductive loads (ie solenoids and relays) is strongly recommended,
however care must be taken to ensure correct polarity connection to these devices.
5.8.4.5.
Defining the status of Outputs (normally closed OR open)
Provision has been added to the circuit to define the state of each output if there is an on-
going fault in the CPU section. The reasoning for this provision is that the user may want
one output to fault to an off position (ie Motion Cut) and another to fault to an on position
(ie External audible alarm). The status is defined using DIP switch SW1 with the switch
position number referring to the respective output. When the switch is “ON”, the
corresponding output will be energised if the CPU fails, or alternatively when the switch is
“OFF” the corresponding output will be de-energised if the CPU fails. This ‘fault state’ can
be selected manually by the user by activating the disable input.
5.8.4.6.
Specifications

5 ampere @ 30 VDC

Input current approx. 6mA @ 24V DC
5.8.4.7.
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.
