The inactivity timer for the front port is set to 15 minutes. This controls how long the unit maintains its level of
password access on the front port. If no messages are received on the front port for 15 minutes, any password
access level that has been enabled is cancelled.
Note:
The front serial port does not support automatic extraction of event and disturbance records, although this data can be
accessed manually.
4.1.3.1
FRONT SERIAL PORT (SK1) CONNECTIONS
The port pin-out follows the standard for Data Communication Equipment (DCE) device with the following pin
connections on a 9-pin connector.
Pin number
Description
2
Tx Transmit data
3
Rx Receive data
5
0 V Zero volts common
You must use the correct serial cable, or the communication will not work. A straight-through serial cable is
required, connecting pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5.
Once the physical connection from the unit to the PC is made, the PC’s communication settings must be set to
match those of the IED. The following table shows the unit’s communication settings for the front port.
Protocol
Courier
Baud rate
19,200 bps
Courier address
1
Message format
11 bit - 1 start bit, 8 data bits, 1 parity bit (even parity), 1 stop bit
4.1.4
FRONT PARALLEL PORT (SK2)
The front parallel port uses a 25 pin D-type connector. It is used for commissioning, downloading firmware updates
and menu text editing.
4.1.5
FIXED FUNCTION LEDS
Four fixed-function LEDs on the left-hand side of the front panel indicate the following conditions.
●
Trip (Red) switches ON when the IED issues a trip signal. It is reset when the associated fault record is
cleared from the front display. Also the trip LED can be configured as self-resetting.
●
Alarm (Yellow) flashes when the IED registers an alarm. This may be triggered by a fault, event or
maintenance record. The LED flashes until the alarms have been accepted (read), then changes to
constantly ON. When the alarms are cleared, the LED switches OFF.
●
Out of service (Yellow) is ON when the IED's functions are unavailable.
●
Healthy (Green) is ON when the IED is in correct working order, and should be ON at all times. It goes OFF if
the unit’s self-tests show there is an error in the hardware or software. The state of the healthy LED is
reflected by the watchdog contacts at the back of the unit.
4.1.6
FUNCTION KEYS
The programmable function keys are available for custom use for some models.
Factory default settings associate specific functions to these keys, but by using programmable scheme logic, you
can change the default functions of these keys to fit specific needs. Adjacent to these function keys are
programmable LEDs, which are usually set to be associated with their respective function keys.
