Maintenance - Riello SC ACS 160 Manual

REPLACING THE CONTROLLER FUSE
b
Replace the fuse with the one contained into the
document envelope.
b
Repairs and maintenance may only be performed
by a specialist. Before working on the unit, switch
off the power supply and secure it against being
switched on again! Check for the absence of power!
b
Only use the supplied spare fuse or a fuse of the
same design with the following specifications: T2A
250V
If the mains voltage is switched on and the controller still
does not function or display anything, then the internal
device fuse may be defective. In that case, open the de-
vice as described under 3.1, remove the old fuse and
check it.
Exchange the defective fuse for a new one, locate the
external source of the error (e.g. pump) and exchange
it. Then first recommission the controller and check the
function of the switch outputs in manual mode.
