Figure 42: Implementation of remote control functionality on Digital Input 1 of the ESI-Manager
WARNING: If a function is assigned to a digital input, the same function must never be
assigned to the other digital input. Otherwise the inverter may behave erratically.
Once the cabling has been finished,
−
The auxiliary fuse box may be closed
−
The inverter top cover may be replaced including the connection of the
ESI-Manager to the master unit
−
The power to the inverter may then be restored
Then, the ESI-Manager has to be used to associate the remote control functionality with
Digital Input 1. This is done by going to the digital input setup menu and selecting
‘Remote ON’ for digital input 1. When this is done the inverter will switch on when the
switch S shown in
is closed and the inverter will switch off when the switch S
is opened. Refer to
Section 7.9.2.4.2
for guidelines on how to navigate to the digital input
setup menu.
Remarks:
−
When the remote control functionality has been activated this function has
priority over a local start/stop command. When the local command has to be
given, deactivate first the remote control functionality by navigating with the
ESI-Manager to the digital input setup menu and setting the digital input
considered to ‘Disabled’.
−
The remote control functionality can also be implemented on the Digital Input 2.
6.13.2 Cabling of alarm functionality
An alarm represents an error condition that makes the inverter trip.
