MODEL 1440-2-3 QUICK START INSTRUCTIONS
1. MOUNTING
• Prepare panel cutout to dimensions shown below.
• Remove instrument from case by turning captive safety screw (2) counter clockwise.
• Grasp the bezel and slide the instrument out of its case (1).
• Slide the supplied rubber gasket over the case.
• Slide the instrument case (1) into the panel cutout.
• Slide the panel mounting bracket over the instrument case.
• Tighten two screws on panel mounting bracket until case is securely mounted in panel cutout.
• Slide the instrument back into the case and tighten safety screw.
2. WIRING
• Connect an appropriate length of either thermocouple extension wire (e.g.Type J), OR 3 wire
RTD leads to the appropriate terminals as shown below.
• Connect Outputs for Heat/Cool. Note that Outputs are jumper selectable for Relay/SSR output.
Refer to Figure 15, Page 22 for jumper location.
• If a current transformer option is to be used for Heater Breakdown Alarm, connect to
appropriate terminals.
• Connect power to the appropriate terminals as shown below.

3. INSTRUMENT CONFIGURATION
• Remove instrument from case by loosening safety screw, grab bezel and slide out of case.
• Refer to Figure 15, Page 22, for jumper selection of Relay/SSR selection and AL1 Cool relay NO/
NC selection. Default factory settings are Main/Relay, AL1 Cool/Relay Normally open.
• Locate jumper V2 in Figure 14, page 21 and place in the open position.
• Slide instrument back in case and apply power. Display will now show CnF.
• Press the FUNC button until P1 is displayed.
• Refer to Parameter List on page 23. Using the UP arrow, select appropriate P1 code for Input
type and standard range.
• Press the FUNC button until next parameter is displayed.
• Repeat for each parameter to be changed.
• When configuration is complete, remove instrument from case, place jumper V2 in the closed
position, return instrument into case and secure with safety screw.
• Apply power to instrument, Upper display will show process temperature, lower display will
show setpoint.
• Using UP and DOWN arrows, temperature setpoint can be adjusted.
• Refer to Manual page 36 in for Control Parameters if PID tuning is required.
• Instrument is now ready for use.
NOTE: The preceding Quick Start instructions are the basic settings required to install, wire, and
get the controller operating. It is assumed that the operator is familiar with PID temperature
controllers. Please refer to the complete installation and operation manual for additional
functions and instructions.
