ZP3-ECU Extinguishing Control Unit Installation and Commissioning Manual
One loop – two zones
Figure 13: One loop – two zones
Based on the example shown in Figure 13 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 zone allocation routine to allocate the following devices:
• 1001 and 1002 to Zone 14
• 1024, 1027, and 1028 to Zone 15
3. Use I/O mapping routine to map the following:
• Zone 14 to operate the extinguishing relay (1025)
• Zone 15 to operate the coincidence connection relay (1046)
4. Program both the extinguishing relay (1025) and the coincidence connection
relay (1046) to single-knock/non-silencing operation mode.
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.
