16.4.1.1 Auxiliary power supply
When there is a PR113 equipped with a dialogue unit, the consumptions of the unit are different from those indicated just for the protection unit.
The values to be considered are given in the following table.
Characteristics
PR113/PD-A Version
Power supply voltage
24V DC ±20%
Maximum ripple
5%
Inrush Current @ 24 V
~5A for 30ms
Start-up Current@ 24 V
~1.0A for 150ms
Continuous current rating @ 24 V
~310mA
Nominal Power @ 24 V
~8W
16.4.2 Inputs/outputs
16.4.2.1
Binary opto-insulated inputs
– CB-Closed:
Status of power circuit breaker
– CB-Open:
Status of power circuit breaker (for congruency control with power CB-Closed)
– CB-Springs:
State of springs
– CB-Position:
Position of power circuit breaker
16.4.2.2
Output contacts
– K51/YC: relay output which can be activated by the user to close the power circuit breaker
– K51/YO: relay output which can be activated by the user to open the power circuit breaker
• Monostable contacts, only active when there is Vaux
• Maximum changeover current: 3A – 250V AC (0.2A – 100V DC)
• Insulation contact-contact voltage: 1000 V AC
16.4.3 Communication bus
– External bus Modbus™ protocol RS485 2-Wire Twisted Pair, 19.2kbit/s max., connection to differential bus (See par.16.3 note B).
16.4.4 Information functions
To access the following pages, see par. 16.6.1.
16.4.4.1
Software version
ABB SACE
This page shows which Software version there is of the dialogue unit of the above PR113/PD unit.
PR113/D-M Sw: x.xx
Each time it is necessary to communicate any operating problems with the dialogue unit to ABB SACE, it is a good
idea to indicate the Sw version of the unit (“x.xx”).
16.4.4.2
Opening data storage
Manual Opens: x x x x x
Sum of openings due to manual openings by means of pushbuttons on the front of the power circuit breaker, controls
coming from opening coil (YO) and undervoltage (MT).
Prot. Trips:
x x x x x
Sum of openings due to protections (L, S, I, G, T temperature, D, A, UV, OV, RV,…).
Other Trips:
