3.3.3
Pulling In the Machine Stop Relay
Once the CHTX has been turned on (as described in
Section 3.3.1 on page 19
or
Section 3.3.2 on page 19
) and is in the normal operating mode, the Machine Stop relay
in the receiver can be pulled in by pushing the OFF/ON/START toggle switch to the
START position and then releasing.
NOTE:
If the unit has a standard status LED, it will illuminate solid red during the
transmitter's power-down process. Once the power-down process is complete, the
transmitter will turn off and the status LED will not be on.
NOTE:
You must place the OFF/ON/START switch to the ON position after the unit is
powered up and then push it to the START position to pull in the Machine Stop relay.
For older CHTX models, it is necessary to position the OFF/ON/START switch into the
START position once to start the transmitter and a second time to pull in the Machine
Stop relay.
3.3.4
Turning Off the Transmitter
The transmitter can be turned off by pressing the OFF/ON/START toggle switch down
to the OFF position. Once the transmitter is turned off, the Machine Stop relay in the
receiver is immediately opened.
NOTE:
If the unit has the standard separate Power/Status LED and Battery LED, the
Battery LED will illuminate solid red during the transmitter's power-down process. Once
the power-down process is complete, the transmitter will turn off and both LEDs will not
be on.
NOTE:
If the unit has a standard single LED, it will illuminate solid red during the
transmitter's power-down process. Once the power-down process is complete, the
transmitter will turn off and the LED will not be on.
NOTE:
Depressing the Machine Stop switch will also turn off the transmitter and open
the Machine Stop relay in the receiver.
See Section 3.4 on page 20
for more
information on the Machine Stop switch.
3.4 Machine Stop Switch (for Emergency Stopping Only)
When the Machine Stop switch is depressed, the Machine Stop relay in the receiver is immediately
opened.
Under normal operating conditions, the Machine Stop switch must be in the raised position. If it is not in the
raised position, the transmitter and system will not operate.
NOTE:
The Machine Stop switch is to be used for emergency stopping only, not for normal
system shutdown.
3.5 Power/Status and Battery LED
The standard CHTX transmitter includes a Power/Status LED to communicate to the operator that the unit
is functioning and also includes a Battery LED to indicate when the battery level is low (
see Section 3.7.1
on page 21
for LED indication definitions).
NOTE:
Single Status/Battery LED-equipped units will indicate that the transmitter is on and the
battery level from the single LED (
see Section 3.7.2 on page 22
for LED indication definitions).
