Digital Communication
For the firing modes : the switch between (FC1, C16, C64, SCA) to (PA or HC16) but not the other
way round. It also allows the change between (FC1, C16, C64 and SCA) or between (PA or HC16)
(see note 7).
For the control modes :
• If the unit is configured in PA, the following changes are allowed :
From U
2
I
2
to I
2
and reciprocally
From U
2
I
2
to UxII
2
and reciprocally (see note 4)
From I
2
to UxII
2
and reciprocally (see note 4)
From Open Loop (OL) or Ué to I2 but not the other way round (see note 5)
From OL or U
2
to U
2
I
2
but not the other way round (see note 5)
From OL or U
2
to UxII
2
but not the other way round (see notes 4 and 5)
• If the unit is configured in burst firing mode, the following changes are allowed :
From V2CL to VICL and reciprocally (this corresponds to a change between the
control modes U
2
and UxI with HC16 firing mode active, see note 2)
From U2 to V2CL but not the other way round (a current limitation is applied with
U2 control threshold, see note 5)
NOTES :
1. On inductive loads FC1 or SCA is automatically switched to in C16 in order to avoid the
2. HC16 = (V2CL + C16) or (VICL + C16) which is a C16 firng mode with current limitation by
threshold (thyristor conduction angle limitation)
3. (U

(UxII

4. In order to be allowed, the out of factory configuration must be UxII

5. When in I
2
or V2CL control mode, it is possible to get back to U2 or OL control mode depend-
ing on the case, after having switched off the unit.
6. When swithching from burst firing mode to phase angle, the control loop is restre to zero in
order toi achieve a ramp start.
When swithching from phase angle to burst of phase angle HC16, a ramp of angle is applied on
the next conduction
7. On a factory configured unit with burst firing mode, and after a change to work in phase
angle, getting back into burst firin mode is only possible after having switched off the unit.
With identical functions, digital communication settings are has priority on factory settings.
Important
On 7300A products, there is no scale control or value validity sent via the digital communi-
cation option. In case of over flow, the value will not be saved.
