8) Safety precautions
To make the handy operator’s panel disconnectable, the handy
operator’s panel enable switch must be mounted on the connection
panel. When the handy operator’s panel is connected, but the handy
operator’s panel enable switch is set to “DISCONNECT,” the
emergency stop and deadman switches on the handy operator’s panel
are disabled. Therefore, when the handy operator’s panel is connected,
do not set the handy operator’s panel enable switch to
“DISCONNECT.” Put up a notice indicating this near the handy
operator’s panel enable switch.
CAUTION
1 While the handy operator’s panel is in use, do not set the
handy operator’s panel enable switch to “DISCONNECT.”
Otherwise, the emergency stop and deadman switches on
the handy operator’s panel will be disabled.
2 While the handy operator’s panel is in use, do not let anyone
else set the handy operator’s panel enable switch to
“DISCONNECT.” One way to accomplish this is to use a
handy operator’s panel with a key attached so that the user
of the handy operator’s panel can keep the key.
3 After the emergency stop switch on the handy operator’s
panel has been pressed, do not reset the emergency stop
by setting the handy operator’s panel enable switch to
“DISCONNECT.”
4 When the handy operator’s panel is not being used (the
handy operator’s panel enable switch is set to
”DISCONNECT”), remove the handy operator’s panel and
put it away so that no one may think that the emergency stop
and deadman switches on the handy operator’s panel are
effective.
Setting the handy operator’s panel enable switch to ”DISCONNECT”
when the handy operator’s panel is connected causes the power to the
handy operator’s panel to be turned off, turning off the display on the
handy operator’s panel.
