8.2.1.
Description of Digital Inputs, Digital Outputs and Relay Outputs.
Digital Inputs
Digital inputs provide switched inputs to the RCI-4100. Digital switched inputs can be used for a
wide range of uses. Examples are (but not limited to):
•
Proximity switches (slew reset, hoist direction, boom angle limit).
•
Inputs from mechanical switches to select different load charts or to reduce SWL e.g.
personnel lift switches, sea state switches.
•
Slew encoder and wind speed inputs.
Digital inputs may be connected to the RCI-4100 controller PCB through IS barriers or DIN rail
mounted terminals in the RCI-4100 enclosure. Digital inputs can be configured as “Normally Open”
or “Normally Closed”, “Switched Positive” or “Switched Negative”. LSI-Robway uses a “Fail/Safe”
philosophy so digital inputs are normally configured to limit crane movements or reduce SWL
unless the switch is powered on.
Digital Outputs
Digital outputs provide switched outputs which are energised during certain conditions under
software control. When a digital output is ‘energised” it provides a negative. Digital outputs are
normally used to activate a DIN rail mounted relay in the enclosure with contacts rated at 5A. They
are not designed to control high power (or many) solenoids, rather they are designed to switch
intermediate relays which are then used to directly switch high power (or many) solenoids. This
relay provides “NO” and “NC” contacts. Digital outputs can be used for a wide range of uses.
Examples are (but not limited to):
•
External audible alarm
•
Boom up, or down motion cut
•
Minimum radius motion cut
•
CW, CCW slew motion cut
LSI-Robway uses a “Fail/Safe” philosophy so digital outputs are normally configured to limit crane
movements or reduce SWL unless energised.
Relay Outputs
Relay outputs provide switched outputs which are energised during certain conditions under
software control. Relay outputs are provided from safety relays mounted on the RCI-4100
controller PCB and are rated at 5A. They are not designed to control high power (or many)
solenoids, rather they are designed to switch intermediate relays which are then used to directly
switch high power (or many) solenoids. The safety relays provide “NO” and “NC” contacts. These
are connected to DIN rail mounted terminals in the RCI-4100 controller. Relay outputs are
normally used for “Motion Cut” and “ATB Motion Cut” but can be used for the same purposes as
digital outputs. LSI-Robway uses a “Fail/Safe” philosophy so relay outputs are normally configured
to use “NO” contacts.
8.2.2.
What are the inputs and outputs on this crane?
The digital inputs, digital outputs and relay outputs are listed in the RCI System Configuration
Documents in Attachments. The GA (General Arrangement drawing) are also in the RCI System
Configuration Documents in Attachments and shows the wiring for the digital inputs, digital outputs
and relay outputs.
NOTE: Some GA’s cover a range of crane configurations. These may include inputs and
outputs not used on this crane. If an input or output is on the GA but does not appear
on the RCI Configuration Sheet it should be ignored.
