One loop – multiple detectors
Figure 12: One loop – multiple detectors
Based on the example shown in Figure 12 above, configure the ECU as follows:
1. Select the two addresses, for example:
• Extinguishing relay = address 025 on loop 1
• Coincidence connection relay = address 046 on loop 1
Refer to "Guidelines to programming the ECU" on page 6 if required.
2. Use the I/O mapping routine to map the following devices:
• 1001, 1004, and 1008 to operate the extinguishing relay (1025)
• 1022 and 1027 to operate the coincidence connection relay (1046)
3. Program both the extinguishing relay (1025) and the coincidence connection
relay (1046) to single-knock/non-silencing operation mode.
4. Verify the programming by triggering two detectors, and one mapped to each
output, and checking that the ECU functions correctly.
WARNING: Make sure that the actuator is disconnected so as not to discharge
the cylinder.
