7- Parameters transfer

211

Portable server

AKO-14918 portable server, with no power

supply, in which parameters programmed in a

255

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

255

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.

211

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-

255

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.

255

Between -40 ºC and +20 ºC, when the NTC probe is extended up to 1.000 m with minimum

255

0,5 mm

cable, deviation will be less than 0.25 ºC (Probe extension cable ref. AKO-15586).
