Programming port:
▪ Used for software updates via Renesas Emulators together with a special PCB
board from Emerson
Status LED (green):
▪ Flashing fast: Fault state
▪ Flashing slow: Standby
▪ Constantly on: Compressor running / heating
Used to select the type of feedback on port B:
▪ Without jumper (variable duty cycle (%):
0: ......... Tripped
100: .... OK
▪ With jumper (variable duty cycle (%):
0: ......... Error (general error, miswiring)
25: ...... Wrong compressor code (power cycle needed)
50: ...... Standby (waiting for enable and 0…10 V signal)
75: ....... SDP mode (Speed-Drop-Protection mode)
100: ..... Running or heating mode
Used for selection of the compressor speed range:
▪ Without bridge between pins 1 and 3
o Limited speed range in normal operation (Mode 0: Full Envelope Protection
selected – see paragraph 4.4 "Envelope control" for more details)
▪ With bridge between pins 1 and 3
o Full speed range in normal operation (Mode 1: High Speed Envelope Protection
selected – see paragraph 4.4 "Envelope control" for more details)
7-segment display:
▪ Displaying status, speed, error code, software version

5.2 Control and configuration
5.2.1 Selection of drive compressor code
The drive compressor code must be selected by a 6-digit binary coded DIP-switch which has to be
done before connecting to the drive. In case of a wrong configuration the 7-segment display shows
the error code E39. The PWM output shows a duty cycle of 25 %. In this case a power cycle is
needed to reset this fault. The DIP-switch will only be analysed once after a power cycle. During the
start-up cycle the 7-segment display will show the compressor as per the DIP-switch configuration –
see Table 14.
Table 14: Package codes for ZPV*/YPV* compressors
The binary code reflects the DIP-switch positions from left to right (from 1 to 6), "1" meaning ON state
for the switch, "0" meaning OFF state for the switch.
Example:
▪ Drive version: EV3185B-K1-294
▪ Compressor version: ZPV096-4X9
▪ Package code: 45
▪ Binary code: 101101
