Installation
 Note:
Field wiring used for
24VDC input must be
suitably rated.
 Note:
Before beginning
leak/pressure testing,
be certain that all
valves are closed.

3.4.6 External HMI (optional)
1. With power off, open the external HMI enclosure.
2. Connect +24 VDC to TB-1, Terminal 1.
3. Connect -24 VDC to TB-1, Terminal 2.
4. Connect proper ground to TB-1,
Terminal 3.
5. To establish proper
communication between
external HMI and Z10000
odorizer an ethernet cable will
need to be provided by the
customer.
6. Open external HMI enclosure
and connect one end of the
ethernet cable to port labeled
MJ2 located on the right side of the HMI controller.
7. Run the ethernet cable though code applicable conduit
from the external HMI to the Z10000 enclosure and
connect the other end to the RJ45 patch panel located
inside the enclosure.
8. Close external HMI access door.
3.5 Leak Testing
After installing the tubing and wiring, all the tubing and fittings
connected to the system need to be leak tested. During leak
testing, pipeline pressure is slowly brought back to the bulk
tank.
1. Apply nitrogen (or pipeline gas or instrument air) to
odorant supply line. Check for leaks on line leading from
the bulk storage tank to the odorizer.
2. Open isolation valve through the software override in
TechView.
3. Check for leaks within the odorizer enclosure.
4. Open valve at pipeline to check for leaks from the
Pipeline back to the odorizer enclosure.
5. Check for leaks back to the enclosure.
6. Place isolation valve back in normal service through the
proper screen in TechView.
