PRODUCT Vehicle Data Recorder and Seat Belt Warning system BY AMS
4.2. Seat Belt Warning Input module (p/n 118093)
The Seat Belt Warning input module (p/n 118093) must be configured for the seat and seatbelt switch operation
(either Normally Open or Normally Closed), “seat bounce” error validation timing (2, 3, 4, or 5 seconds), and the
module address (either address 1 or address 2).
Open the Seat Belt Warning input module to gain access to the switch configuration switches and the address
configuration jumper.
4.2.1. Input type configuration
The inputs for the seats and the seatbelts are designed for ground polarity. The configuration switches set the
input type: NC = Normally Closed, NO = Normally Open (default). The “seat” configuration switches are labeled
with an “S” and the seat position number, and the “seatbelt” configuration switches are labeled with a “B” and the
seat position number. For example, the seat and seatbelt switches for seat position 2 are labeled “S2” and “B2”.
 The Normally Closed (NC) configuration is for inputs that are open when the seat (or belt) switch is activated.
 The Normally Open (NO) configuration is for inputs that are closed when the seat (or belt) switch is activated.
4.2.2. “Seat bounce” error validation timing
The default time for the “seat bounce” error validation (see section 5.1.2) is two seconds. This time can be
increased to three, four, or five seconds by placing switch configuration switches 1, 2, or 3 into the ON position. If
all three switches are in the OFF position then no time is added to the default timing of two seconds. Each switch
turned to the ON position adds one second to the default timing. For example, if switches 1 and 2 are set to the ON
position then the “seat bounce” error validation timing is set to four seconds (two default seconds plus two added
seconds).
4.2.3. “Leaning in seat” and “seat and belt tie” error validation
Software versions 1.3 and later.
Switch configuration switch 4 sets the “leaning in seat” and “seat and belt tie” error validation. Set the switch to the
OFF position to configure a tight error validation or set the switch to ON to configure a loose error validation.
Leaning in seat error validation
The system will set an error condition (red) when the seat and belt were previously cycled correctly, but now the
seat switch has been de-activated for longer than the “seat bounce” timing (2-5 seconds).
