The initial and full scale values determine the input

span which is used by the PID algorithm, the

SMART and the alarm functions.

NOTE: the minimum input span (S = P4 - P3), in

absolute value, should be set as follows:

For linear inputs, S

> 100 units.

For TC input with °C readout, S

> 300 °C.

For TC input with °F readout, S

> 550 °F.

For RTD input with °C readout, S

> 100 °C.

For RTD input with °F readout, S

> 200 °F.

P5 = Output 1 type

rEL = Relay [the cycle time (Cy1) will be forced to

15 s]

SSr = SSR [the cycle time (Cy1) will be forced to

4 s]

P6 = Output 1 action.

This parameter is skipped if P7 = 4

rEV = Reverse action (Heating action)

dir = Direct action (Cooling action)

P7 = Output 2 function.

0 = output not used.

1 = it is used as alarm 1 output and the alarm 1

is programmed as process alarm.

2 = it is used as alarm 1 output and the alarm 1 is

programmed as band alarm.

3 = it is used as alarm 1 output and the alarm 1 is

programmed as deviation alarm.

4 = it is used as second control output (Cooling

output).

NOTE: setting P7 = 4, the P6 parameter is forced

to "rEV".

P8 = Cooling media.

Available only when P7 = 4

AIr = Air is used as cooling media.

OIL = Oil is used as cooling media.

H2O = Direct water is used as cooling media.

Changing P8 parameter, the instrument forces the

cycle time and relative cooling gain parameter to the

default value related with the chosen cooling media

When P8 = AIr - Cy2 = 10 s and rC = 1.00

P8 = OIL - Cy2 = 4 s and rC = 0.80

P8 = H2O - Cy2 = 2 and rC = 0.40

P9 = Alarm 1 operating mode

Available only when P7 is equal to 1, 2 or 3.

H.A. = High alarm (outside for band

alarm) with automatic reset.

L.A. = Low alarm (inside for band alarm) with

automatic reset.

H.L. = High alarm (outside band) with manual

reset (latched).

L.L. = low alarm (inside band) with manual reset

(latched).

P10 = Option feature ( see also "Display

function" and "OUT 1 failure detection")

OFF = No option

SP2 = Digital input for SP / SP2 selection.

n.O. = Set P10 to n.O. when the load is
