10 Maintenance

 

PCS-9785 Satellite-Synchronized Clock

 

10-1 

Date: 2019-07-05 

This device is designed to require no special maintenance. All measurement and signal 
processing circuit are fully solid state. All input modules are also fully solid state. The output relays 
are hermetically sealed. 

Since the device is almost completely self-monitored, from the measuring inputs to the output 
relays, hardware and software defects are automatically detected and reported. The 
self-monitoring ensures the high availability of the device and generally allows for a corrective 
rather than preventive maintenance strategy. Therefore, maintenance checks in short intervals are 
not required. 

Operation of the device is automatically blocked when a hardware failure is detected. If a problem 
is detected in the external measuring circuits, the device normally only provides alarm messages. 

10.1 Appearance Check 

  The device case should be clean without any dust stratification. Case cover should be sealed 

well. No component has any mechanical damage and distortion, and they should be firmly 
fixed in the case. Device terminals should be in good condition. The keys on the front panel 
with very good feeling can be operated flexibly. 

  It is only allowed to plug or withdraw device board when the supply is reliably switched off. 

Never allow the CT secondary circuit connected to this equipment to be opened while the 
primary system is live when withdrawing an AC module. Never try to insert or withdraw the 
device board when it is unnecessary. 

  Check weld spots on PCB whether they are well soldered without any rosin joint. All dual 

inline components must be well plugged. 

10.2 Failure Tracing and Repair 

Failures will be detected by automatic supervision or regular testing. 

When a failure is detected by supervision, a remote alarm is issued and the failure is indicated on 
the front panel with LED indicators and LCD display. It is also recorded in the event record. 
Failures detected by supervision are traced by checking the “

Superv State

” screen on the LCD. 

When a failure is detected during regular testing, confirm the following: 

  Test circuit connections are correct 

  Modules are securely inserted in position 

  Correct DC power voltage is applied 

  Correct AC inputs are applied 

  Test procedures comply with those stated in the manual
