Setup and Adjustments
Controller Configuration DIP Switch and
LED Mode
A DIP switch configures the HE-6800 for use with the
desired controller by enabling or disabling the manual
override PB and the LED. To change the controller mode,
use the three position DIP switch located on the PCB. See
Figure 4 and consult Table 2 to determine the controller
compatibility.
For all transmitter models, the factory default LED mode
is
LED Mode:ON
. The DIP switch positions enable/disable
the functions listed in Table 3
NOTICE
Risk of Property Damage
Do not use switch settings other than those shown
in Figure 4. Using other switch settings may cause
incorrect controller operation or damage to the
element, controller, [and/or] controlled equipment.
