Output Power Request (OP) :
Corresponds to the duty ratio value in bust firing mode or
to the conduction angle in phase angle firing mode.
Read value between 0 and 255.
Process Value (PV) :
Represents the selected parameter value for the regulation system.
Read value between 0 and 255.
Working Setpoint (SP) :
Corresponds to result of the product between the setpoint local and the setpoint limit
with Bit 1 OS = 1 SP = (SL * HS)/255
(Read value between 0 and 255)
or
is the result of the product between the remote input and the high local limit
with Bit 1 OS = 0 SP = (RI * HL)/255
(Read value between 0 and 255)
Power (PW) :
Corresponds to the output power of the power thyristor unit after possible recalibration.
Only present if U*I option chosen. Read value between 0 and 255.
Voltage value (VV) : Read value between 0 and 255.
Current Value Channel 1 (C1) : Read value between 0 and 255.
Current Value Channel 2 (C2) : Read value between 0 and 255.
Current Value Channel 3 (C3) : Read value between 0 and 255.
Current Value (CV) :
Mean value of the three currents : CV = (C1+C2+C3)/3
Read value between 0 and 255
Remote Input (RI) :Read value between 0 and 255
Local Limit (LL) :
Value of the potentiometer (Ilim) on front panel.
Limit Setpoint (LS) :
Represents the current recalibration. Corresponds to the result of the product between the
digital current limit (CL) and the local Limit (LL) :
LS = (CLxLL)/255
Recalibration cannot be less than 20% of the nominal current of the power unit.Read value
between 51 and 255.
High Local Limit (HL) :
Value of the local setpoint limit. Adjustable by ‘VIlim’ potentiometer. Read value between 0
and 255.
Delay Triggerring (DT) :
Value of the first firing delay in degree. Adjustable by ‘DLY’ potentiometer
Read value between 0 and 90.
