Attention!
To meet CE Mark requirements for all units
intended for use in the EU or in high electrical
noise environments, all electrical cables
must be installed as described in Appendix
A, “CE Mark Compliance and High Noise
Environments”.
To wire the analog outputs, complete the following steps:
1. Disconnect the main power and remove the rear cover.
2. Install a cable clamp in the chosen conduit hole on the
side of the electronics enclosure.
3. Refer to Figure 13 on page 14 to locate the correct
terminal block, and wire the analog outputs as shown.
Secure the cable clamp.
Note: Analog outputs 1 and 2 in the wiring diagram
correspond to analog outputs A and B in Slot 0 in the
Panaview software.
4. If wiring of the unit has been completed, reinstall the rear
cover on the enclosure and tighten the set screw.
WARNING!
Make sure both covers, with their o-ring seals,
are installed and the set screws tightened
before applying power in a hazardous
environment.
Note: Prior to use, the analog outputs must be set up and
calibrated.
Proceed to the next section to continue the wiring of the
PanaFlow Z1G/Z2G Process Gas Flowmeter .
2.4.4 Wiring the standard RS485 serial port
The PanaFlow Z1G/Z2G Process Gas Flowmeter is equipped
with a standard RS485 serial interface. This serial port will be
used to communicate with PC/DCS system. In addition, the
PanaFlow Z1G/Z2G Process Gas Flowmeter can receive and
execute remote commands, using Panametrics’s PanaView
software.
Note: For more detailed information on serial
communications refer to Panametrics’s EIA-RS Serial
Communications manual (document #916-054).
Attention!
To meet CE Mark requirements for all units
intended for use in the EU or in high electrical
noise environments, all electrical cables
must be installed as described in Appendix
A, “CE Mark Compliance and High Noise
Environments”.
Refer to Figure 13 on page 14 to locate the correct terminal
block, and wire the RS485 serial port as follows:
WARNING!
Always disconnect the line power from the
PanaFlow Z1G/Z2G Process Gas Flowmeter
electronics before removing either the front
or rear cover. This is especially important in a
hazardous environment.
1. Disconnect the main power and remove the rear cover.
2. Install the required cable clamp in the chosen conduit
hole on the side of the electronics enclosure.
3. Feed one end of the cable through the conduit hole, wire
it to terminal block, and secure the cable clamp. Use
the information in Table 2 below to prepare a suitable
cable for connecting the PanaFlow Z1G/Z2G Process Gas
Flowmeter to the external serial device.
