Another possibility is the following:. To change a parameter value operates as follows:. Enter the Programming mode. Select the required parameter. NOTE : the set value is stored even when the procedure is exited by waiting the time-out to expire. Keep pressed for more than 3 s the and keys. At this point it will be possible only to see the set point or the MAX o Min temperature stored.

To switch the instrument on again press the SET1 key. Down Scale. Full Scale. Hy1 Intervention differential for set point1 -Full Sc. It can be set with positive value or with negative value. Hy2 Intervention differential for set point2 : -Full Sc.

LS1 Minimum set point1: Down Sc. LS2 Minimum set point2: Down Sc. Sets the maximum acceptable value for set point1. Sets the maximum acceptable value for set point2. ALC Alarms configuration: it determines if alarms are relative to set point1 or referred to absolute values. ALU Maximum alarm:. NOTE: the decimal point selection is not available on models with thermocouple input.

UdM Measurement unit: it depends on models:. PbC Probe selection: it sets the kind of probe. It depends on models. LAO Lower analog output limit : only for models with analog output minimum value of temperature associated to the 4mA analog output.

UAO Upper analog output limit : only for models with analog output maximum value of temperature associated to the 20mA analog output. SAO Analog output safety with probe fault : only for models with analog output determines what state the analog output should assume when the probe is faulty:. Digital input polarity:. Parameters table: read only Shows the code of the parameters map. Software release: read only. To access the Pr2 parameter programming menu. Instrument XTC and XTC shall be mounted on vertical panel, in a 29x71 mm hole, and fixed using the special brackets supplied.

To obtain an IP65 protection grade use the front panel rubber gasket mod. Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. Let air circulate by the cooling holes. The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5 mm 2.

Separate the input connection cables from the power supply cables, from the outputs and the power connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a suitable external relay. All models can be connected to the monitoring and supervising system XJ using the serial port.

The external XJ serial module to interface the instrument with the monitoring and supervising system XJ is required. Program one controller with the front keypad. Turn OFF the instrument. After 10 seconds the instrument will restart working with the new parameters. The controllers have 1 free contact digital input. This function allows to invert the regulation of the controller for both the outputs: from direct to inverse and viceversa.

The alarm stops just after the digital input is de- activated. The relay outputs are switched OFF. The alarm will stop as soon as the digital input is de- activated. This function is enabled until the digital input is activated. Probe broken or absence.

Probe short circuited. Maximum temperature alarm. Alarm output ON; Other outputs unchanged. Minimum temperature alarm. External alarm. Output unchanged. Serious external alarm. Output OFF. Status of the instrument. Instrument off. Normal operating. Alarm present. Once the alarm signal is detected the buzzer, if present, can be disabled by pressing any key. The display signal remains as long as the alarm condition remains. Check connections before replacing the probe. Housing: self extinguishing ABS.

Connections: Screw terminal block 2,5 mm 2 heat-resistant wiring. Set point1. Set point2. Differential 1. Minimum set point1. Down Sc. Minimum set point2. Maximum set point1. Maximum set point2. Output configuration. Action type output 1. Action type output 2. Anti-short cycle delay:.

Minimum time a stage stays switched ON. Minimum time between 2 following switching ON of the same load. Alarm configuration. Start Sc. Alarm recovery differential. Alarm delay. Alarm delay at start up. Out1 status with faulty pr. Out2 status with faulty pr. Alarm relay disabling. Alarm relay polarity. Lci 2. Start scale with current or voltage input. Uci 2. End scale with current or voltage input. Probe calibration.

Measurement unit temp. Kind of probe. Aoc 3. Analog output configuration.
