User manual - CONTROLLER PUR-94

This parameter can be set from 0 to 99.9% (for active current output and active

voltage output) or from 0 to 29.9% (for passive current output).

Parameter

“Hi r”

defines higher border of the range due to formula:

Out

max

+ (

× “

Hi r

” %), where:

– higher signal value range limit.

This parameter can be set from 0 to 19.9% (for active and passive current

output) or from 0 to 9.9% (for active voltage output).

In example on page

of the

DISPLAY VALUES CALCULATION

paragraph

the procedure of the analogue outputs determining is presented in details.

“

”

- this parameter determines the behaviour of analogue output if any critical situation

occurs. According to version of the device, this parameter can be set:

For active current output:

“noCH”

- current will not change,

“22.1”

- current will be set to 22.1 mA,

“3.4”

- current will be set to 3.4 mA,

“0.0”

- current will be set to 0 mA.

For passive current output:

“noCH”

- current will not change,

“22.1”

- current will be set to 22.1 mA,

“3.4”

- current will be set to 3.4 mA,

For active voltage output:

“noCH”

- voltage will not change,

“11.0”

- voltage will be set to 11 V,

“5.5”

- voltage will be set to 5.5 V,

“1.2”

- voltage will be set to 1.2 V.

“0.6”

- voltage will be set to 0.6 V,

“0.0”

- voltage will be set to 0 V.

When the critical situation goes, the output signal will be set to value calculated due to

formulas given above.
