6.3.11 Troubleshooting Advanced Pulse Modules
Equipment Required
:
Pulse Generator
Voltage Generator
Frequency Counter
Jumper wire
PC running ROCLINK 800 software
Caution
Failure to exercise proper electrostatic discharge precautions, such as
wearing a grounded wrist strap may reset the processor or damage
electronic components, resulting in interrupted operations.
To verify high-speed operation:
1.
Disconnect the field wiring at the APM module terminations.
2.
Connect to ROCLINK 800 software.
3.
Select
Configure
>
I/O
>
Advanced Pulse Module
. The Advanced
Pulse Module screen displays.
4.
Select the correct Pulse Input Point Number.
5.
Connect a pulse generator having sufficient output to drive the
module to terminals PI1 through PI4 and COM. The pulse generator
must synthesize a square wave signal of 50% for every cycle.
6.
Connect a frequency counter across terminals PI1 through PI4 and
COM.
7.
Set the pulse generator to a value equal to, or less than 10 kHz.
8.
Set the frequency counter to count pulses.
9.
Verify (using ROCLINK 800 software) that the count read by the
counter and the ROC800 are the same.
10.
Remove the test equipment and reconnect the field device.
6.3.12 Network Radio Modules
To verify connectivity of the Network Radio Module:
1.
Check the module status and LEDs if you are already configured and
joined to a network.
2.
Verify COM status for the commissioned devices by looking at the
RL800 RTU commission list.
3.
Verify that Access Points have unique settings for the Network ID
and Channel.
