Tamper Switch
Install the wires in the cable from the tamper switch into the two-pin connector provided in
the connector kit, and plug the connector into J1 of the first or only PC232-S4-X converter
board. If using two PC232-S4-X units, only a single tamper switch connection is needed.
Fuses
The fuse located in the PC232-S4-X PCBs is 1 A, 3AG, SloBlo (Littelfuse® PN 313001).
Current Loop Converter, Routine Maintenance
•
Vacuum the current loop converter every six months, or more often if the unit is located
in a dusty environment.
•
Check the continuity of the grounding circuit periodically.
Testing Communications
This test assumes that all hardware and software is installed. (Refer to the
P2000
Server/Workstation Software Installation Manual [Part No. 24-10618-120]
for instructions.)
Monitor the status of loops, controllers, and terminals by using the P2000 System Status
window (located in the
System
menu). Refer to the
P2000 Software User Manual (Part No.
24-10618-147)
for more information.
Use visual checks to help verify that the system is working properly. Use the two wiring
diagrams, in Figure 4 and Figure 5, as troubleshooting aids.
•
LED2 through LED9 on the PC232 PCB flicker when operating correctly.
•
If the LEDs on the PC232 PCB do not flicker, verify that all cables are constructed
correctly and securely attached.
•
If LED1 is lit, the board is receiving power. If not, verify power is flowing from the main
source to the PC232.
