Two loops with one zone in each loop
Figure 10: Two loops with one zone in each loop
Based on the example shown in Figure 10 above, configure the ECU as follows:
1. Select the two addresses, for example:
• Extinguishing relay = address 005 on loop 1
• Coincidence connection relay = address 026 on loop 2
Refer to “Guidelines to programming the ECU” on page 6 if required.
2. Use the zone allocation routine to allocate the following devices:
1001, 1002, and 1004 into Zone 14
2021, 2022, and 2025 into Zone 15
3. Use the I/O mapping routine to map the following:
• Zone 14 to operate the extinguishing relay (1005)
• Zone 15 to operate the ECU coincidence connection relay (2026)
Programme both the extinguishing relay (1005) and coincidence
connection relay (2026) to single-knock/non-silencing operation mode.
4. Verify the programming by triggering a detector in each zone and checking
that the ECU functions correctly.
WARNING:
Make sure that the actuator is disconnected so as not to discharge
the cylinder.
