3.6 Optional Graphic User Interface
The optional LCD screen located at the center of the device provides visual information during the
operation of the CHTX transmitter. It is used to change configuration settings, confirm commands being
operated, provide two-way feedback, and display transmitter diagnostic information such as battery life
and signal strength.
The optional graphic user interface replaces the standard status LED when ordered.

3.7 Normal Operating Mode with Standard Status LED(s)
In normal operating mode, the CHTX uses the Power/Status and Battery LED(s) to communicate the
watchdog timer within the CPU of the transmitter, the machine stop relay status, and when the battery level
is low.
3.7.1
Transmitters Equipped with Separate Power/Status and
Battery LED Indicators
3.7.1.1 Watchdog Indicator (Steady Slow Flashing Green Power/Status
LED)
The blinking Power/Status LED represents the watchdog timer within the CPU of the
unit. This indicates that the transmitter is powered on.
NOTE:
The Power/Status LED should be continuously flashing at all times. If the LED
is not flashing, the transmitter will need to be rebooted to operate properly.
3.7.1.2 Machine Stop Relay Indicator (Rapidly Green Flashing Power/
Status LED)
When the receiver is online with the transmitter and the machine stop relay is
successfully pulled in, the Power/Status LED will rapidly flash green.
NOTE:
If the receiver inactivity timer times out, the transmitter will revert back to the
watchdog indicating status (steady slow flashing green Power/Status LED). Follow the
procedure for pulling in the Machine Stop relay in
Section 3.3.3 on page 20
. It will
resume rapidly flashing the green Power/Status LED if the Machine Stop relay is
successfully pulled in.
NOTE:
This LED function is only available on the 2.4 GHz and 900 MHz-equipped
transmitters. On 433 MHz-equipped transmitters, the watchdog indicator function in
Section 3.7.1.1 on page 21
continues to operate after the Machine Stop relay is pulled in.
