6 PKE-SWD-CP, Connection for circuit-breaker PKE
6.10 Programming
150 SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com
The value in data field I-REL-MAX can also be read as an acyclical object
(￫ Section 6.10.3, „Acyclic data PKE-SWD-CP“, page 153).
6.10.1.7 Thermal model (TH)
The PKE motor-protective circuit-breaker will use the selected current range
and actual power flow to calculate the unit's thermal state on the basis of the
implemented trip type. The PKE-SWD-CP module will provide this thermal
state in the form of an input byte. It will be represented as a relative value
within a range of 0% to 255% (0x00 to 0xFF).
The PKE will trip if the thermal model assumes a value of 110%.
The value in data field TH can also be read as an acyclical object (￫ Section
6.10.3, „Acyclic data PKE-SWD-CP“, page 153).
6.10.1.8 Type of trip block (TYPE)
The modular design of the PKE electronic motor-protective circuit-breaker
enables several different current ranges to be covered. A different PKE trip
block is inserted into the PKE basic device depending on the current range
required.
The following trip blocks of the type PKE-XTU(W)ACP-… can be combined
with the two PKE basic devices PKE32 and PKE65.
Table 28: Combination options of the PKE basic device with PKE trip block
The type of PKE trip block is mapped via the TYPE bit field (input byte 4,
Bit 0 - 2). The values of this bit field are assigned to the following PKE trip
blocks:
PKE-XTU(W)ACP-36 PKE-XTUACP-65
Minimum current value 7.2A 14.4A
