Installation
 Note:
Wiring the High Speed
Counter Input to the
Z10000 power strip is
not recommended as this
increases the potential
for signal interference.
6
3. Connect -24 VDC to TB-1, Terminal 6.
4. Connect proper ground to ground bus bar located inside
the enclosure.
5. Close the electronic access door.
6. Connect conduit per applicable code.
3.4.2 Wiring Termination
Alarm Output
Sends a pulse to the RTU to notify regarding an alarm state.
• TB-2, Terminal 7: +, 4–28 VDC
• TB-2, Terminal 6: -, 4–28 VDC
Pulse Output
Used to monitor odorant usage by sending pulses to an RTU /
external counter after a set volume has passed.
• TB-2, Terminal 5: +, 4–28 VDC
• TB-2, Terminal 6: -, 4–28 VDC
High Speed Counter Input
Used for pulsed flow signal.
• TB-2, Terminal 11: +, 4–28 VDC
• TB-2, Terminal 10: –, 4–28 VDC
3.4.3 Flow Signal and Level Gauge Signal
If you are using a 4–20 mA flow signal and/or level gauge
signal, wire the connections to the second terminal block as
follows:
Gas Flow Signal
• TB-2, Terminal 12: +, 4–20 mA
• TB-2, Terminal 13: -, 4–20 mA
Tank Level
• TB-2, Terminal 14: +, 4–20 mA
• TB-2, Terminal 13: -, 4–20 mA
3.4.4 Modbus RS-485 Wiring
Modbus RS-485 protocol is used to monitor the real time status
of the Z10000 natural gas odorizer. Wire the connections to the
third terminal block as follows:
• TB-3, Terminal 5: +, RS-485
• TB-3, Terminal 4: -, RS-485
3.4.5 I/O Signal Verification
The TechView I/O page allows verification of I/O signals to the
Z10000. The status of DI and DO pins can be seen and verified.
See the image below for an example of the I/O screen.
