Wiring Notes:
1. Maximum wire size is 16 AWG.
2. Input voltage range is 20.4 to 26.4 VDC. Midas
pyrolyzers and transmitters with LonWorks
modules have a restricted minimum voltage
requirement of 21.6 VDC.
3. It is mechanically possible to misalign Plug1
and Plug2. Care must be taken when inserting
plug to assure correct alignment.
4. Plug1 and Plug2 are internally connected in
parallel to facilitate wiring in bus topology.
5. LonWorks
®
FT-10 wiring is polarity sensitive.
Lon A and Lon B may be swapped.
10.1.3 Configuring the Midas
®
for LonWorks
®
1. Turn on 24 VDC power.
2. Confirm that the Midas
®
initiates the power up
sequence.
3. Reset Fault F49 if present.
4. Set alarm levels and other parameters as
desired.
5. Confirm that the Midas
®
IP parameters are at
default values. If changed, the DHCP client
must be set to ‘n’. The IP address must be
restored to 169.254.60.47 and the subnet
mask must be restored to 255.255.255.0
