7- Parameters transfer
Portable server
AKO-14918
portable server, with no power
supply, in which parameters programmed in a
powered controller can be copied by transfer.
Parameters can be transferred again from the
server to other identical powered controllers.
Storage dump or fast copy of the para-
meters entered in the portable server
to the controller:
Press the key
while the controller is being connected to the power supply until the dis-
play shows
CPY
, indicating that the transfer was made correctly. Disconnect the controller
and reconnect it to the power supply.
Storage dump can also be done from parameter L6=2.
8- Maintenance
Clean the controller surface with a soft cloth, soap and water. Do not use abrasive deter-
gents, petrol, alcohol or solvents.
9- Warnings
The use of the unit without observing the manufacturer's instructions may alter its safety
qualification.
To ensure correct operation of the apparatus, only NTC type probes supplied by AKO should
be used.
Between -40 ºC and +20 ºC, when the NTC probe is extended up to 1.000 m with minimum
0,5 mm
2
cable, deviation will be less than 0.25 ºC (Probe extension cable ref.
AKO-15586
).
REMARK:
When time parameters are modified, the new values are applied when the current
cycle is completed. In order for it to have an immediate effect, switch the controller off and
then on again.
