Safe-E-
Stop™
User Guide
The Status LEDs of other PSDs (if any) will flash orange. The display will show ESTOP #, where # is the number
of the issuing PSD. The PSD will vibrate three times.
6.4.5 Recovery of an E-Stop
To recover following an E-Stop, the problem requiring the E-Stop must be satisfactorily resolved. The PSDs that
issued the E-Stop need to release their E-Stop switches, after which the MSD E-Stop Safety Relays will close and
the machine can be reset to restart operations.
6.5 Leaving an E-Stop Group
An active member of the E-Stop group may have reason to leave an operation, such as completing work, needing
a rest break, changing shift, etc.
Members may leave the group at any time without causing an E-STOP or COMM LOSS by following a simple
procedure that informs the MSD that the PSD user wants to leave the group in a controlled and safe way.
The user simply needs to press and h
old the ‘O’ button for more than 1 second until the Status LED begins
flashing, then release the ‘O’ button for slightly more than 0.5 seconds, then press the ‘O’ button again for at least
1 second. The PSD will then unlink from the MSD. Note that if the ‘O’ button is not pressed a second time within 5
seconds, the PSD will return to normal operational state. This process ensures a PSD is not accidentally unlinked.
When the PSD transitions to the unlinked state the PSD vibrates once to confirm and the LCD d
isplays “LINK?
Hold I.”
6.6 Switching OFF the PSD
From the unlinked state, the PSD will power down after 60 seconds without input. The PSD can also be powered
down manually by holding the ‘O’ button for three seconds.
Note that if the PSD is in Error state it will power off after 3 minutes.
6.7 Charging the Battery
1.
Ensure the charging adapter is connected to a power socket.
2.
Connect the adapter to the charging cradle.
3.
Insert the PSD into the cradle.
4.
Ensure the power to the charging adapter is switched on and the LED on the adapter is illuminated.
5.
Battery charging now begins.
6.
The PSD battery charging process will be completed within approximately3 hours.
6.7.1 Battery Capacity and Operating Life
The battery in the PSD will slowly degrade over time and will reach 80% capacity after approximately 500 charge/
discharge cycles, reducing the maximum run time of the PSD. Other factors affect the run time of the PSD,
including temperature; very low temperatures will significantly reduce available battery capacity. At -20°C the
capacity will be approximately 30% lower than at 25°C.
Cattron recommends that the customer estimate the usage of their PSDs in order to plan for a battery
replacement after 500 charge/ discharge cycles.
The battery is not user serviceable. The PSD must be returned to Cattron or an authorized agent for service.
