iSd2

External alarm with manual restore from digital input 2
Solutions:
• check the causes of input activation
• see parameters i5 and i6
• wait for the cause of the alarm to disappear and then

press the

and

keys for 1 s

Main consequences:
• the relays used for regulation will be forced to the state

established with parameter i11

• if parameter CFG is set at 3, the relays signalling the alarms

and errors will be switched on

When the cause of the alarm disappears, the device restores normal
operation, except for the following alarms:
• the external alarm with manual restore from digital input 1 (code

“iSd1”)

• the external alarm with manual restore from digital input 2 (code

“iSd2”)

which require the cause of the alarm to disappear and successively the
keys

and

to be pressed for 1 s.

ERRORS

10.1

Errors

CODE MEANING

Pr1

Probe 1 error
Solutions:
• see parameter P01
• check the integrity of the probe
• check the device-probe connection
• check the magnitude detected by the probe
Main consequences:
• the work Program function cannot be activated
• the work program will be interrupted if it is in progress
• the relays used for regulation will be forced to the state

established with parameter C4

• if parameter CFG is set at 3, the relays signalling the alarms

and errors will be switched on

Pr2

Probe 2 error
Solutions:
• see parameter P02
• check the integrity of the probe
• check the device-probe connection
• check the magnitude detected by the probe
Main consequences:
• if parameter P9 is set at values different to 0 (or if the CFG

parameter is set at 8 or 9), the device will function as if the
parameter is set at 0

• if parameter CFG is set at 3, the relays signalling the alarms

and errors will be switched on

• If the CFG parameter is set at 8, the relays used for

adjustment will be forced to the state established with
parameter C5

When the cause of the alarm disappears, the device restores normal
operation.
