BOGE – RATIO compressor control for screw compressors
Control Parameterization1.5
Parameter overview
The control is already set for a bus coupler (BOGE-Bus-Address 32) for each
compressor according to customer specifications – as e.g. for Profibus. If
used another communication of RS485 then the following action is necesarry:
1. Enter Code 830 as described under parameterization → the display shows
one of the following fig. c or d.
2. Press ↑ or ↓-key to select the picture (bobus = BOGE-Bus, rtu = Modbus
type RTU) and quit by ↵-key. Depending upon selection one of the two
following fig. appears e or f:
With the BOGE-Bus only the desired address (flashing here 32) is to be
selected and quit by ↵-key, while with the Modbus-RTU after confirmation
of the address (flashing here on 0 = offline) by the key ↵, if address >0,
still additionally the Baud rate and the data format are adjustable as fol-
lows fig. g:
first the number 96 (= 9600 Baud) flashes – after confirmation by the ↵-
key 8E1 flashes (8E1 = 8 data bits, parity check of Even and 1 stop bit).
By means of key ↑ or ↓ then the necessary combination can be selected
(n = not parity check, o = odd).
3. Press ↵-key to overwrite the non-volatile EEPROM with the blinking value,
and the main display reappears.
A blinking Online symbol refers to a fault in the RS485 connection.
