After checking the system, check the points below up to operation.
No.
1 Do the capacity of the main power supply on/off unit and wiring span meet specification?
2 Is the specified power supplied to the Lossnay power terminal (TM1)?
3 Is the wiring length of the transmission cable within specifications?
When using PZ-41SLB-E:
When using M-NET:
4 Does the transmission cable meet regulations? (Type, diameter)
5 Is the transmission cable wired at least 5 cum away from the power supply cable?
6 Are multiple transmission or signal cables wired to the same power cable duct?
7 Are multiple transmission cables wired with multi core cables?
8 Is the transmission cable connected to the terminal unit?
(PZ-41SLB-E to TM4 1, 2; M-NET to TB5
9 Is the transmission cable securely connected to the Lossnay terminal unit?
10 When not using M-NET
If using 1 Lossnay unit, is the Main/Sub change switch (SW1) on the Lossnay circuit board set to "Main"?
If using 2 or more Lossnay units, is the Main/Sub switch set to "Main" on only one unit, and the other units are set
to "Sub"?
11 When using M-NET
Is the address switch on the Lossnay circuit board (SA1, SA2) set to the correct number?
12 When using external control input
Do the specifications of the external signal match specifications of signals that can be input to the Lossnay?
13 When the external input signal is a pulse signal
Is the pulse input switch (SW2-2) on the Lossnay circuit board set to ON?
14 When the external signal is 12V DC, 24V DC, or Mr. Slim (A-control or K-control) signal
Is it connected to 1, 2 on the Lossnay external control input terminal unit (TM2)?
15 When the external signal is an uncharged a-contact signal
Is it connected to 1, 3 on the Lossnay external control input terminal unit (TM2)?
16 When M-NET is not being used
Is the external input signal connected to the Lossnay set to "Main"?
17 Is the signal cable length within wiring specifications?
12V DC, 24V DC signal:
Uncharged a-contact signal:
Mr. Slim (A-control or K-control) signal: Within 500 m
18 Is the signal cable wired at least 5 cum away from the power supply cable?
19 Is the output capacity of the Lossnay operation monitor/malfunction monitor (pre-heat output) within specifications?
Operation monitor output:
