DMODE = 1
DMODE = 0
Note: 0 to 10V output signal is available for 699 Plus A1 electronics (code 00.03.010.0010).
J) Analog output connection scheme for code 00.03.010.0010:
Analog Signal A1 = from 0 to 10V
AGND = analog signal GND
NOTE:
In order to obtain the best accuracy from the instrument’s analog output signal it is mandatory to connect 699Plus
analog output to the Inverter’s input, considering its input characteristics:
A) Inverter with floating input: 2 wire connection
E.g. Inverter
699Pus A1
Pin 11
Analog Common
AGND
GND
Pin V2

B) Inverter with differential input: use 3 wires to connect the lift’s Inverter to 699Plus analog output, i.e.:
1. Connect JP11.1 and JP11.2 to 699Plus’s screw terminal analog output GND at the 699Plus's end.
2. Connect JP11.3 to Analog Output signal.
E.g. Inverter
699Pus A1
JP11.1
