Operations Overview; Battery Switch - Atlas Copco XAMS 1150 CD7 T3 APP Instruction Manual

OPERATIONS OVERVIEW

It is possible to control the compressor locally with
the Control Box, remotely with the remote switch
inputs located on the back of the Control Box, or with
software running on a PC with a CAN interface (PC
Control Mode).
The way one ends up in each status can differ from
how the Control Box is controlled, but the function of
each status stays the same.
When reading this document, mind the difference
between a status and a procedure. A status is a state in
the Control Box's operation. A procedure is an action
executed by the Control Box.
Example: The Stopping procedure is executed in the
Stopping status, the Start Failure status and the
Shutdown status.
During operation
When the engine is running, the air
outlet valves (ball valves) must always be
in a fully opened or fully closed position.
The doors must be closed during
operation and may be opened for short
periods for inspection and adjustments
only.
Regularly carry out following checks:
1. Ensure that the regulating valve (RV) is correctly
adjusted, i.e. starts decreasing the engine speed
when reaching the preset working pressure in the
receiver.
2. Check the air outlet temperature of the
compressor element.
3. Check the engine oil pressure, the coolant
temperature and display of control box.
4. Avoid the engine running out of fuel.
Nevertheless, if this happens, fill the fuel tank and
prime the fuel system to speed up starting (see
section Specific start procedure).

BATTERY SWITCH

The compressor is equipped with a battery switch.
When the compressor is not in use this switch must
always be switched off.
It is not allowed to use this switch as an emergency
switch or for stopping the compressor. It will cause
damage in the control unit when using this switch for
stopping.
Always first shut off the control unit and wait until the
display is dark before switching the battery switch
off.
Please be aware that the (optional)
preheater unit is still "live" with the
battery switch switched off.
