9 Faults and Warnings
Danger
Risk of electric shock from charged capacitors
Always disconnect the system from the power
supply and then wait a further 10 minutes
before touching electrical components. The
power capacitors require this time to discharge.
9.1 Checklist
Loose connections, plugs, a faulty power supply or
failure to observe information/instructions can give rise
to a considerable number of fault displays. The faults
indicated, therefore, may frequently be attributed to
another cause.
Therefore, please always observe the following
checklist:
1) The system’s supply voltage must be within the
permissible limits.
2) The control power transformer must be set to any
differing local rated voltages (see electrical circuit
diagram).
3) The control cabinet temperature must not exceed
50 °C.
4) All remote controls fitted at a late date (e.g. remote
on/off) must be managed without a connection
relay at max. 20 metres from the control cabinet.
5) Before starting up and performing maintenance
work, make sure that all connection screws are
tight and that all plugs are firmly connected.
6) Power supply cables must be of adequate cross-
section. When rating the cable(s), therefore, pay
attention to the cable-laying method, line length
and line temperatures to be expected.
7) When retro-fitting switchgear, the control-power
transformers must not, under any circumstances,
be tapped as they could be overloaded.
8) Only use genuine Gardner Denver replacement
parts.
9) Do not connect additional switchgear or measuring
equipment without the approval of Gardner Denver.
10) Do not route measuring sensors out of the system.
11) If you have any technical queries, have the
following information to hand so that a fault can be
rectified quickly and methodically:
System type / factory number
Re-order
ref.
Circuit diagram, drawing no. and ID no.
Information on the system's operating conditions
Information on any accessories you have
subsequently installed (remote controls, etc.)
Other subsequent modifications or attachments
to the system.
The fault number and description of the fault that
has occurred.

How the Fault and Warning Codes
are Structured
Error codes always begin with a letter followed by a
number. They are further divided into compressor errors
and VSD errors as detailed in the table below.
9.3
Tables of Faults and Warnings
The following tables show details of possible warnings
and faults which may occur on the GD Pilot TS, with
their possible cause and suggested remedial action.
