Operation Steps
Operate the gas detector by taking the following steps.
1. Set the IP address/Unit ID.
Modbus TCP communication requires that the 4th value of the IP address to be set.
RS-485 communication requires the Unit ID (slave address) to be set.
Remove the address plate to access the DIP switches and set the IP address or Unit ID.
Before turning on the gas detector, check that all wiring is correct. Refer to 6-1.
“Wiring
Procedure” and your delivery specifications if your unit has end-user-specific options.
Pull the center of the plate with finger
to remove it from the base unit.
DIP switches are accessible when
the plate is removed.
Set the base unit power switch to the OFF position before using the DIP switches to
avoid incorrect operation or device failure.
Do not use IP address “255 (1111 1111)” because LAN Communication will be disabled if
that IP address is used.
When using the 24 VDC power supply, ensure that the power is 24 VDC
10%.
When using the PoE power supply, ensure that the LAN cable is securely connected.
Check that the target gas type and full scale value are correct before using a new sensor
unit. Also, check that the sensor unit expiration date has not been reached.
