Safety Systems | Safe-D-Stop™
1. Wire Your Machine Control Unit (MCU)
The MCU terminalsand pin numberingrelative to the OCU buttons are identified
in the system configurationdrawing provided with your system.
1. In almost all cases the implementationof an appropriate mainline contactor
power circuitis required using K18 and K19 to maintainthe Machine power
and possibly K20 to reset the Machine, althoughthis may be a local reset.
2. Connect power and ground (per system specification)to J1 via a local
disconnect switch.
3. Connect the correct antennas to the antenna connectors.
4. Check the wiring and turn on the MCU power, the MCU LEDs, two power
green, Heartbeat flashingred and statusamber, the relays K18 and K19 will
energize if all is OK.
2. Charge or Install the Batteries
Rechargeable OCUs have tamperproof
screws on the battery cover. Disposable
battery (AA type) OCUs have cross head
screws on the battery cover.
3. Turn on the Operator Control Unit (OCU)
1. Press the ON button, this will
wake the OCU from sleep to
a fully tested PASSIVE non-
transmittingmode.
2. You will see all LEDs flash
briefly and the Haptic buzz to
confirm they are all working.
3. The center Status and Right-
hand LEDs 1 & 2 will then
illuminate

4. Move to Active Mode
NB: For 2.4GHz Systems OCUs musthave completedthe Associationprocess with its
target MCU (this only needs to be done once, see the user manual)
From Passive Mode the OCU can be moved into an Active mode;
1. Press the Stop Switch and then press the On switch within 3 seconds.
2. The Status E-Stop LED will now flash showing it is transmitting.
3. At this point the OCU is active, and the target machine will be under direct control.

5. Activate a D-STOP
From ActiveMode the OCU can triggeran D-STOP simplyby pressing the
illuminatedE-Stop button.
The Relays K18 and K19 will open and the machinewill stop.
To recover from an D-Stop follow Step 4 to move back to ACTIVE Mode and
restart the machine.

6. Communication Loss when in Active Mode
Whenin Active mode if the OCU is taken out of RF range or if there is strong RF
interference, or if the OCU battery goes flat,the MCU will issue an D-STOP opening
K18 and K19, this is a safety feature to protect against communicationfailures.
In the case of a communicationloss D-STOP, ensure batteries are OK then move back
into range and restart the OCU as in Steps 3 & 4, then restart the machine.
7. De-Linking the OCU
From Active Mode the OCU can be moved into a Passive (disconnected) mode without causing an D-Stop
using Cattron’s patented de-linkingprocess.
From ActiveMode, Press and hold the Start switch , then press and release the STOP switch, then release
the Start switch.
The OCU is now disconnectedand K18 and K18 remain closed
To reconnect the OCU follow steps 3 and 4.
