6.14.1 Cabling of remote control functionality
The ESI-S has the possibility to be controlled by remote control. An example of this
approach is a drive that is switched on at a location and which automatically gives a start
command to the inverter. When the drive is then stopped, the drive sends automatically
a stop command to the inverter too. This section gives an example of how the cabling
has to be done on the inverter side.
Any of the two digital inputs on the ESI-Manager (Cf.
) can be used to cable the
remote control functionality. The electrical requirements of the digital inputs are given
in
(inverter characteristics section).

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.
