The emergency stop state is regarded when the handy operators panel is
in the following conditions:
1) The emergency stop button is pressed on the handy operators panel.
2) When the deadmans switch enable switch is set to the enable state,
both the deadmans switches are released.
3) During connection with the handy operators panel, communication
from the handy operators panel is interrupted. Whether the handy
operators panel is connected or not is determined by two signals
ATCH1 (CRS1015) and ATCH2 (CRS1016).
4) The 24 V is not applied to EMGTP (CRS1011) of the handy
operators panel. An emergency stop is regarded as being set on a
machine operators panel connected to an upper unit of the handy
operators panel, or an emergency stop is regarded as being caused by
turning off another emergency stop contact such as the door open limit
switch.
When the emergency stop state is determined in the handy operators
panel:
1) The 24V output from EMGDN (CRS1012) of the handy operators
panel is stopped.
2) The emergency stop is posted to the Power Mate through
communication.
NOTE
The handy operators panel (Type B) just has an emergency
stop button, but does not determine the emergency stop
state.
Detach the handy operators panel, and connect the emergency stop lines
that are connected via the handy operators panel. If the emergency stop
state is released, the handy operators panel is faulty.
The possible causes are as follows:
1) The emergency stop button on the handy operators panel is left
pressed down.
Release the emergency stop button.
2) The deadmans switch enable switch is set to the enable state, and both
the deadmans switches are released.
Set the deadmans switch enable switch to the disable state.
Alternatively, hold one of the deadmans switches.
