2150EX AV Flow Module - Isco

2150EX Area Velocity Flow System
Section 2 Preparation and Installation
Connects to a 2150EX
Connects to an
RS232EX or
RS485EX
Isolator Cable
Figure 2-18 EX Network Cable for Connection to an Isolator Cable
To connect the EX Network and RS232EX isolator cables:
1. Remove the protective cap from the communication
connector on the top of the 2150EX module.
2. Store the protective cap in the holder next to the connector.
3. Push the 6-pin end of the EX Network cable onto the communication
connector on the top of the 2150EX module.
Use care, so you do not misalign the pins and cause
any short circuits.
4. Route the cable as shown in Figure 2-1, so the other end of
the EX Network cable is at the interface of the safe and
hazardous areas.
5. Attach the hazardous area end of the RS232EX isolator
cable to the EX Network cable coming from the 2150EX.
Use care, so you do not misalign the pins and cause any
short circuits! Attach the other end of the RS232EX cable
to the appropriate port on your computer.
Note
You can safely connect and disconnect the RS232EX cable
from the EX Network cable without removing the 2150EX module
or the EX Network cable from the potentially explosive
atmosphere.
2.6.2 Connecting to a
Computer for
Interrogation
The 2150EX module can be connected to a computer located in a
safe area, using Isco’s Flowlink software (see Figure 2-1). In
order for the 2150EX to communicate with a computer, the two
must be connected by an Isco RS232EX Isolator Cable (P/N
60-2004-339). The hazardous area end, labeled with proper
entity parameters, connects to the EX Network cable. This
enables you to update the 2150EX’s software without entering
the potentially explosive atmosphere.
