13 USE THE HOT KEY
13.1
HOW TO PROGRAM THE HOT KEY FROM THE INSTRUMENT
(UPLOAD)
Program a controller by using the keypad.
1.
When the controller is ON, insert the "Hot Key" and push UP key.
2.
The "uP" message will appear, followed a by a flashing "Ed" label.
3.
Push SET key and the "Ed" will stop flashing.
4.
Turn OFF the instrument, remove the "Hot Key" and then turn it ON again.
NOTE: the "Er" message will be displayed in case of a failed programming operation. In this case push
the UP key if you want to restart the upload again or remove the "Hot Key" to abort the operation.
13.2
HOW TO PROGRAM AN INSTRUMENT USING HOT KEY
(DOWNLOAD)
1.
Turn OFF the controller.
2.
Insert a programmed "Hot Key" into the 5-PIN plug and then turn the controller ON.
3.
The parameter list present into the HOTKEY is automatically downloaded into the controller
memory. The "do" label will blink followed a by flashing "Ed".
4.
After 10 sec the controller restarts, loading the newer parameters.
5.
Remove the "Hot Key".
NOTE: the "Er" message is displayed in case of a failed copying operation. In this case turn the controller
off and then on again (if you want to retry the operation) or remove the "Hot Key" to end the operation.

ALARM RECOVERY
Probe alarms P1, P2 and P3 starts some seconds after the fault in the related probe; they automatically
stop some seconds after the probe restarts normal operation. Check connections before replacing the
probe. Temperature alarms "HA", "LA", "U2" and "L2" automatically stop as soon as the temperature
returns to normal values.
Alarms "EA" and "CA" (with iF=bL) recover as soon as the digital input is disabled.
