When the transmitter is turned on, it performs a
self-test to be sure that the circuitry is within
designated parameters. If an error is detected, the
transmitter will not transmit any motion signals.
The BMS-2 receiver display will show "0 0 4" indicating
a passive E-Stop condition in the transmitter.
Receiver Safe Mode
The following conditions cause the receiver to go into
its Safe mode:
• Radio signal interference
• Transmitter out of operating range
• E-Stop button is activated
• E-Stop circuit failure
• Low battery sends E-stop after time out
When the transmitter is turned off, the Time Out
process begins. The Time Out period is set to 450
msec at the factory. If the receiver does not establish
contact with the transmitter within that time period, it
goes into the Safe Mode. In Safe Mode, the receiver
shuts off power to the output modules and activates the
E-stop function.
The BMS-2 receiver display will show "0 0 1" indicating
an E-Stop condition in the receiver.
NOTE: For descriptions of other display codes, see the
Operation Section of this manual, the Diagnostic
Display Codes table on page 16, or the technical
documentation supplied with your radio remote control
system.
