at which it is turned off (in engineering units).

A1t1

A2t1

A3t1

A4t1

Alarm Time t1. Defines the temporization time t1, in

seconds, for the alarms. Defines the temporization time

t1, in seconds, for the alarms time functions.

The value 0 (zero) disables the function.

A1t2

A2t2

A3t2

A4t2

Alarm Time t2. Define intervalo de tempo t2 para a

temporização nos acion

amentos dos alarmes. Em

segundos.

O valor 0 (zero) desabilita a função.

flsh

Flash. Allows visual signalization of an alarm occurrence

by flashing the indication of PV in the operation level.

The user chooses which alarms are to be associated

with this feature.

SCALE LEVEL

Type

Input Type. Selects the input signal type to be connected

to the process variable input. Refer to Table 2 for the

available options.

Necessarily the first parameter to be configured.

fltr

Digital Input Filter. Used to improve the stability of the

measured signal (PV). Adjustable between 0 and 20. In

0 (zero) it means filter turned off and 20 means

maximum filter. The higher the filter value, the slower is

the response of the measured value.

Dp.po

Decimal Point. Selects the decimal point position to be

viewed in both PV and SP.

vnIt

Unit. Temperature indication in ºC or ºF. Not shown for

linear inputs.

Parameter presented when used temperature sensors.

0ffs

Sensor Offset. Offset value to be added to the PV

reading to compensate sensor error.

Default value: zero.

Spll

Setpoint Low Limit. Defines the SP lower limit of.

For the linear analog input types available (0-20 mA, 4-20

mA, 0-50 mV and 0-

5 V), defines the minimum PV

indication range, besides limiting the SP adjustment.

Defines lower limit for range retransmission PV and SP.

Spxl

Setpoint High Limit. Defines the upper limit for adjustment

of SP.

For the linear analog input types available (0-20 mA, 4-20

mA, 0-50 mV and 0-

5 V), defines the maximum PV

indication range, besides limiting the SP adjustment.

Defines upper limit for range retransmission PV and SP.

1eov

Percentage output value that will be transfer to MV when

the SAFE output function is enabled. If

1eov

= 0, the

SAFE output function is disabled and the outputs are

turned off in the occurrence of a sensor fail.

bavd

Digital communication Baud Rate selection, in kbps: 1.2,

2.4, 4.8, 9.6, 19.2, 38.4, 57.6 and 115.2

prty

Parity of the serial communication.

none

- Without parity

Euen

- Even parity

0dd

- Odd parity

Addr

Slave Address Selection. Identifies the controller in the

network. The possible address numbers are from 1 to

247.

I/O CYCLE (INPUTS AND OUTPUTS)

ovt1

I/O 1 Function: Selects the I/O function to be used at I/O

1 (relay 1).Refer to Table 3 for functions.

ovt2

I/O 2 Function: Selects the I/O function to be used at I/O

2 (relay 2).Refer to Table 3 for functions.

ovt3

I/O 3 Function: Selects the I/O function to be used at I/O

3 (relay 3).Refer to Table 3 for functions.

d.in1

Digital Input Function (DIGITAL INPUT). As Table 4.

CALIBRATION CYCLE

All of the input and output types are calibrated in the factory. If a

recalibration is required, this should be carried out by a experienced

personnel. If this cycle is accidentally accessed, pass through all the

parameters without pressing the

or keys

pass

Input of the Access Password.

This parameter is presented before the protected cycles.

See item Protection of Configuration.

(alib

Allows instrument calibration.

Yes

- Perform calibration

NO - Do not perform calibration

inL(

Input Low Calibration. See section MAINTENANCE /

Input Calibration.

Enter the value corresponding to the low scale signal

applied to the analog input.

ink(

Input High Calibration. See section MAINTENANCE /

Input Calibration.

Enter the value corresponding to the full scale signal

applied to the analog input.

rstr

Restores the factory calibration for all input, analog

output and remote SP, disregarding modifications carried

out by the user.

Adjusts the of cold junction temperature value.

Pas.(

Allows defining a new access password, always different

from zero.

Prot

Sets up the Level of Protection. See Table 6.

Freq

Mains frequency. This parameter is important for proper

noise filtering.

PROTECTION OF CONFIGURATION

The controller provides means for protecting the parameters

configurations, not allowing modifications to the parameters values,

avoiding tampering or improper manipulation.

The parameter Protection (

PROt

), in the Calibration level,

determines the protection strategy, limiting the access to particular

levels, as shown by the table below.

Protection level Protected cycles

1 Only the Calibration level is protected.

2 Outputs and Calibration levels are protected.

3 Scale, Outputs and Calibration levels are protected.

Alarm, Scale, Outputs and Calibration levels are

protected.

5 R&S Program, Alarm, Scale, Outputs and Calibration

levels are protected.

6 Tunning, R&S Program, Alarm, Scale, Outputs and

Calibration levels are protected.

Operation (except SP), Tunning, R&S Program,

Alarm, Scale, Outputs and Calibration levels are

protected.

Operation, Tunning, R&S Program, Alarm, Scale,

Outputs and Calibration levels are protected.
