8.1 Overview
Human machine interface (HMI) is an important component of the equipment. It is a convenient facility to access the relay from the front local control panel of this relay to view desired information, such as measurement quantity or binary inputs’ state or program version etc. or modify some system settings or protection settings. This function is very helpful during commissioning before putting the equipment into service.
Furthermore, all above functions can be realized in a remote terminal with special software through a communication bus via a RS-485 port or an Ethernet port.
This chapter will describe human machine interface (HMI), menu tree and LCD display of the equipment. In addition, how to input settings using keypad is described in detail.
8.1.1 Design
The human machine interface consists of a human machine interface (HMI) module which allows the communication as simple as possible for the user. The HMI module includes:
z A 240×128-dot matrix backlight LCD visible in dim lighting conditions for monitoring status, fault diagnostics and setting etc.
z Twenty LED indicators on the front panel of this relay for denoting the status of this protection operation, the color and trigger condition of each LED can be configured through PCS-PC. z A 9-key keypad on the front panel of the device for full access to the device.
z An Ethernet interface special for the PCS-PC configuration tool; for more details, see the PCS-PC online help brochure or the PCS-PC configuration tool instruction manual.
The front panel of the device is shown in Figure 6.1-2.
8.1.2 Functionality
z The HMI module helps to draw your attention to something that has occurred which may activate a LED or a report display on the LCD.
z You as the operator may have own interest to view a certain data.
z Use menus navigate through menu commands and to locate the data of interest.
8.1.3 Keypad and Keys
The keypad and keys on the front panel of the equipment provide convenience to the operator to view a certain data or change the device’s setting. The keypad contains nine keys, and each key has different function to the other one.
Key Sign Description
“▲”, “▼”, “◄”, “►” Move between selectable branches of the menu tree. “+”, “–” Change parameters or settings.
GRP Fast change the setting group number.
ESC Exit the present level menu to main menu, or cancel present operation. The following figure shows the keypad and keys.

8.1.4 LED indications
There are twenty LED indicators, which can indicate the operation state of the device. The LED_03 to LED_20 is configurable through the PCS-PC configuration tool auxiliary software, and the following figure shows the default LED configuration on the front panel of the device.

Label Display Remarks
Off When this relay is not energized or any hardware defect is detected during self-supervision.
HEALTHY
Steady Green When this relay is in service and ready for operation. Off When this relay is in normal operating situation. ALARM
Steady Yellow When any abnormality alarm is issued.
Off When this relay is in normal operating situation. TRIP
Steady Red When any protection element is operated. Off When this relay is in normal operating situation. RECLOSE
Steady Red When the auto-recloser operates. Off When the circuit breaker is closed state. CB OPEN
Steady Red When the circuit breaker is opened state. Off When the circuit breaker is opened state. CB CLOSE
Steady Green When the circuit breaker is closed state. NOTE!
z The “HEALTHY” LED can only be turned on by supplying power to this device again or rebooting this device.
z The “ALARM” LED is turned on as long as alarm exists. When alarm signals disappear, it will be turned off.
z The “TRIP” LED is turned on once any protection element operates and keeps being on even after the trip command goes off.
z The “RECLOSE” LED is turned on once auto-recloser operates and remains keeps being on even after the auto-reclosing command goes off.
z The “CB OPEN” LED is turned on once when the circuit breaker is in open position. z The “CB CLOSE” LED is turned on once when the circuit breaker is in closing position.
z The “TRIP” and “RECLOSE” LEDs and relevant latched binary outputs can be reset by pressing the key “ENT”+“ESC”, by energizing the binary input [BI_RstTarg] or by executing the submenu “Reset Target”.
