Clearing the optical and acoustic signals (FAULT) takes place automatically after the fault is removed.
The FAULT acoustic signalling is dis-actuated after pressing the backlit ACKNOWLEDGEMENT button.
Information regarding the detected faults is provided on the display. If, during 10 minutes from the
latest registered fault occurrence, there is no new fault, the LCD display is dis-actuated. If the display is
dis-actuated, the currently detected faults may be viewed after pressing the FAULT push button. Then
the display will present fault messages. If the number of messages exceeds the display capability, they
may be scrolled using the same push button or ↓↑ push bunons.
The exception from this rule are non-maskable faults in (properly programmed) monitoring circuits of LK
monitoring lines or the EKS-4001 monitoring and controlling elements whose messages are
automatically presented on the display until they are cleared.
If a printer is provided for operation, a message regarding a given fault will be printed on a paper tape
after it is detected.
8.2.1 Fault types
