6.0 MAINTENANCE
This chapter provides periodic maintenance procedures and assembly replacement procedures. If
troubleshooting is required, refer to the schematic diagrams in Chapter 3 for schematic representations of
Sageon 200A circuits. A list of spare and replacement parts is located in Chapter 7.
IMPORTANT:
Regularly monitor the LEDs on the operator panel, and rectifiers. Review the alarm log
regularly to detect minor problems before they become significant problems.
6.1 CIRCUIT BOARD HANDLING
Semiconductors such as ICs (integrated circuits), diodes, and transistors must be protected against
damaging electrostatic discharges. A properly grounded wrist strap must be worn whenever a circuit
board is handled or touched. A service kit with a wrist strap and static dissipative work mat is available
from both mail order and local electronic supply companies.
Always store circuit boards in anti-static bags.
6.2 PERIODIC MAINTENANCE
Perform the following periodic maintenance procedures at least twice a year.
1.
Thoroughly review the alarm log at the operator panel or at a local or remote PC. Look for repetitive
alarms, determine their cause(s), and take steps to correct events that result in alarms.
2.
Check operator panel LEDs. Refer to Chapter 4, Configuration and Operation for details.
3.
Check all rectifier LEDs. Refer to Section 4.3 for details.
4.
Check all electrical connections. Check that all breakers and fuses are fully seated. Tighten
connections as required. Seat breakers and fuses as required. Look for signs of overheating, arcing,
and accumulation of dust, dirt, and other contaminants. Refer to Chapter 2 Installation and the
drawing package at the back of the manual for factory installed and customer installed connections.
WARNING
Electrical shock and arcing hazard
Hazardous voltage can cause death or serious injury.
Use extreme care when performing maintenance on an
operating Sageon 200A.
Use insulated tools. Remove watch and jewelry.
5.
Verify the Sageon 200A configuration and all parameter values. Refer to Chapter 4 Configuration
and Operation for operator panel and PC screens.
6.
Confirm that all alarm annunciators are functioning. Refer to Chapter 4 Configuration and Operation
for operator panel and PC screens.
7.
Verify BLVD parameter values. Refer to Chapter 4 Configuration and Operation for operator panel
and PC screens.
