Note
The compressor is controlled using a remote start / stop
switch. If the compressor shuts down during operation
due to a power loss, it will not restart automatically
when the power is restored. The remote switch must
first be switched to
“O
ff
”
and then back to
“O
n
”
before
the compressor will restart.
Enabling Remote Start
Connect the potential-free contact that you need for the
remote start / stop function to the corresponding
terminals (see circuit diagram supplied with your
compressor).
This input is permanently programmed for the remote
start / stop function.
This function can be activated via the
Settings >
Control > Remote Start Enabled
menu option.
When the remote start / stop function is enabled, the
message
Attention: Start by Remote
Control...
appears on the screen and the
Home
page indicates
Remote Start Enabled
.
Fig. 41 “Remote Start Enabled Activated” indication
The “Start” and “Stop” buttons on the GD Pilot TS will
no longer have any effect but the emergency stop
button still remains operational.
The machine can now only be switched on and off
using the potential-free contact.
12.5 Remote On-load/Off Load
Danger
In this operating mode, the compressor may start
up automatically at any time.
Caution
Only potential-free contacts may be connected
to the terminal strip. External voltages will
destroy the GD Pilot TS.
The potential-free contacts must not be more
than 20 metres away from the terminal strip. If
necessary, coupling relays must be fitted in the
control cabinet.
The GD Pilot TS controller allows the operator to switch
the compressor into On-load or Off-load from a remote
point through the connection of two potential-free
contacts. This function is needed when using an
external controller, for example.
To activate the function, go to
Settings >
Programmable Inputs and Outputs...
. In this
menu item you must programme an output for the
Enable Remote Load
function and another output for
the
Remote Load
function.
For example:
The
Enable Remote Load
function could be
assigned to programmable input 2 and the
Remote
Load
function could be assigned to programmable input
3. This would be indicated on the
Home
page as follows:
As long as the
Enable Remote Load
function is
activated (input 2), the On-Load/Off-Load command is
given exclusively via the
Remote Load
input (3), while
all other internal pressure setpoints are ignored.
If the line pressure exceeds the set rated pressure by
more than 0.5 bar due to a permanent
Remote Load
signal, the warning A606:
Line Pressure high
is
displayed. This will disable the
Remote Load
input
until the warning is reset.
