Designation
Function
S1, S2
Button to configure the parameters: CAN-ID, CAN-
Baud and CAN-Master (see »Configuration«)
H1, H2, H3,
H4
LEDs (yellow) to indicate the relay states or to dis-
play the configuration values;
e.g. relay K1 tightened -> LED H1 glows (operation
mode)
MD
LED (green) for indicating the device mode.
Operation mode -> LED glows permanently (flashes
during CAN communication);
Configuration mode -> LED uses long and short
flashes to announce the selected parameter (see
»Configuration«)
K1
Closed when CAN bus is connected and the »Safe
Receiver« is not reporting an error; open upon re-
ceipt of CAN error messages or no feedback from
the CAN. CAN error messages that do not cause a
shutdown of the receiver are discarded after 1 se-
cond.

Closed when BT radio connection between foots-
witch and receiver is in Connect or Sniff Mode; open
when wireless connection is not established or no
feedback from CAN.
K3
Closed when the status of the foot switch corre-
sponds to the switching state of the receiver relays;
open when the states are different or no feedback
from CAN.
K4
Closed if the battery voltage is higher than 3.40 V;
open in case of undervoltage (<3.34 V) or no feed-
back from CAN
Configuration
