5. Press any push button on the transmitter handset to operate the equipment. When a
button is pressed, the Status LED will flash orange with a variable speed dependent on
how far the button is pressed. The further a button is pressed, the faster the LED will flash.
When no buttons are pressed, the Status LED will slowly flash green.
6. In case of an emergency, pressing down on the red emergency stop button will
immediately disconnect the receiver E-Stop and turn off the unit. To reset the emergency
stop button, turn the red button either clockwise or counterclockwise and then cycle power
to the unit.
7. After a period of inactivity (push button not pressed) defined by the dip-switch, the receiver
E-Stop will be disconnected and the unit must be power cycled before being turned on
again.
8. Turn off the transmitter power by turning the power key counterclockwise to the OFF
position. The Status LED displays a solid red for 4 seconds. This will disconnect the
transmitter power and the receiver E-Stop altogether. Turn it further counterclockwise to
release the key.
5.2 Changing Transmitter Batteries
Refer to the Enrange Flex EM/EX/Pro Transmitter ATEX/IECEx Information sheet (198-80210-0010)
for a list of batteries approved for use with the Flex HazLoc system.
Change the transmitter batteries by unscrewing the battery cover located on the backside of the
transmitter (refer to Fig. 9 and Fig. 10). During battery installation, make sure that the ribbon is centered
between the two batteries. After changing the batteries, also make sure that all screws are tightened to
avoid water, moisture, dirt, grease, or other liquid penetration.
