3.2 DISPLAY DESCRIPTION

Upper Display

The upper display continuously shows the process variable in amperes. During the programming
procedure, this display shows the numerical value of the selected parameters or functions.

Lower Display

The lower display continuously shows the current set point value. Pressing the ▲ pushbutton for less
than 1.5 seconds causes the heater consumption in amperes to be shown. Pressing the ▲

pushbutton again causes the set point value to be re-shown. During configuration, calibration, and
parameter setup, the lower display will show the code of the selected parameter.

12

3.3 KEYBOARD DESCRIPTION

Selects the parameters. Pressing the FUNC pushbutton causes the
parameters to be shown sequentially on the upper and lower displays.
Simultaneously, the value of the previous parameter will be stored.

In operating mode, the SMRT pushbutton enables or disables the SMART
function. In configuration and calibration mode it is used to scroll the
configuration and calibration parameters backwards without storing the
modified value.

Decreases the parameter value. When the instrument is in operating mode,
it allows direct access to the set point modification.

Increases the parameter value. When the instrument is in operating mode,
it allows the display of the heater consumption or direct access to the set
point modification.

Loads the default control parameters.

Turns the control output

or On.

4. ALARMS

4.1 MAIN ALARMS

Two independent alarms are available, each of which can be configured in one of three modes, as
follows:

• Process alarm

• Band alarm

• Deviation high or deviation low

Action: Direct or Reverse Action
Threshold resolution: 1 digit
Alarm hysteresis: Programmable between 0.1% and 10.0% of the input span
Alarm indication: Two LEDs (Al1, Al2) lit for alarm ON

Alarm 1: See Outputs, page 18
Alarm 2: Relay output with SPST contact;
contract rating 2 A/250 VAC with resistive load

1440 Microprocessor-based Temperature Controller 13

4.2 HEATER BREAKDOWN ALARM

This function uses a measurement (in amperes) of the main load consumption along with a user-set
alarm threshold to indicate either a partial or complete heater malfunction. This alarm output is
linked to Alarm 2 with a logical OR.

NOTE: This is supplied with the current transformer input option.

Threshold resolution: 1 digit
Alarm hysteresis: 1 digit
Alarm indication: LED Al2/HB flashes when alarm is On
Alarm output: See Alarm 2

5. MOUNTING

Select a mounting location where there is minimum vibration and the ambient temperature range is

between 0 and 50°C. The instrument can be mounted in a panel up to 15 mm thick with a

rectangular cutout of 45 x 92 mm. To mount the Model 1440, insert the instrument through the
panel cutout. While holding the instrument against the panel, slide bracket over case and tighten the
screws until the instrument is held tightly against the panel (see figure 2).

5.2 CUTOUT DIMENSIONS

Figure 4 shows the panel cutout dimensions of the Model 1440.

Fig. 4 Cutout Dimensions

5.3 VERTICAL PACKING

The minimum distance between cutouts is 20 mm.

Horizontal Packing for More Instruments in a Single Cutout

The total dimension of the cutout is the addition of the front dimensions minus 3 mm. The horizontal
dimension of the cutout equals (n x 48) - 3 mm, where n is the number if instruments to be packed
(maximum 10 instruments).

6. WIRING GUIDELINES

Connections should be made with the instrument housing installed in its proper location. Figure 5
illustrates the rear terminal block of the Model 1440.

Fig. 7 Thermocouple Input Wiring

NOTE: DO NOT run input wires together with power cables. For TC wiring, use proper

compensating cable, preferable shielded. If shielded cable is used, it should be grounded at
one point only.

Figure 8 illustrates the RTD input wiring for the Model 1440.

Fig. 8 RTD Input Wiring

NOTE: DO NOT run RTD wires together with power cables. If shielded cable is used, it should be

grounded at one point only. Use copper wires of appropriate size (see Product
Specifications). The resistance of the three wires must be the same

Any external components (e.g., zener barriers) connected between sensor and input terminals may
cause errors in measurement due to excessive and/or unbalanced line resistance or possible leakage
currents.
