Control Block
The main control block of the GT1 control panel is located under the center of the touch-screen. It consists of 1 on/off switch, 3 LEDs and the infrared receiver port. The infrared port is the connection to the wireless keyboard used during programming.
The On/Off switch is used to switch the control panel on and off or to initiate a forced switch-off. If a fault occurs that causes the unit to "lock-up", you can shut down the unit by holding down the on/off button for 5 seconds. This may cause the loss of operating software, necessitating a reinstall (use only in an emergency).
The status of the switch does not affect the charging operation.
The "temperature" LED will glow red when the control panel is overheated. The control panel will shut down approximately 10 seconds later. See the Owner's Manual for restart procedures.
The "battery" LED will glow yellow during charging. It will switch off to signify the battery is fully charged. It will flash yellow if excessive temperatures continue.
The "operation" LED will glow green when using an external power source, glow orange when using the internal battery. A flashing orange LED signifies a discharged battery.
Alternately flashing orange/green LED denotes that the internal battery is defective or has been removed.
