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
Analog Input Analog Signal Analog Signal
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
0V
JP11.2
AIN- AGND
GND
JP11.3 AIN+

WARNING: POWER SUPPLY MINUS, provided to 699Plus instrument is NOT the AGND analog output
ground.
