Maintenance
Maintenance involves configuring and verifying essential features of the relay. These features may be
programmed through the front panel controls or through the communications ports. The following list of
these features includes the corresponding commands in parenthesis. LCD contrast cannot be adjusted
through the communications ports. Output contact testing cannot be performed through the HMI.
• Time and date settings (TIME, DATE, PCLK)
• Communication port settings (COM)
• Password settings (PW)
• Fault detector calibration settings (CAL, FREQ)
• HMI liquid crystal display (LCD) contrast
• Default HMI display screen (PDISPLAY)
• Output contact testing (OUT)
• Software version reporting (VER)
