The N450D is a digital temperature controller in 1/16 DIN size with 2 outputs for control and
alarm. The four digit display is used for temperature indication as well as for parameter
configuration. Easy to configure, the N450D is intended for use in heating or cooling
applications, delivering accurate temperature measurements with excellent immunity to
electromagnetic fields. A large variety of sensor types are available (J, K, T, Pt100, etc).
CAUTION or WARNING:
Read complete instructions prior to installation
and operation of the unit.
CAUTION or WARNING:

SAFETY SUMMARY
The symbols below are used on the equipment and throughout this document to draw the
user's attention to important operational and safety information.

SPECIFICATIONS
Notes:
- Pt100 sensors are connected to terminals 8, 9 and 10. For full compensation of cable resistance, only cables
with equal wire electrical resistance should be used. For 2 wire Pt100, short circuit terminals 9 and 10.

This instrument has three modes: LEVEL 1, LEVEL 2 & LEVEL 3. LEVEL 2 & LEVEL 3 can
only be changed during system setting and parameter change. The operation of changing
mode is listed below according to the LCK selected in parameter setting.
1. Press key once to enter LEVEL 1 mode;
2. Press and hold key for more than 2.5 s to enter or exit from LEVEL 2 mode;
3. Press and hold and keys for more than 2.5 s to enter or exit from LEVEL 3 mode.
This instrument has a display auto-recovery function. It will automatically change back to main
display mode whenever the display setting is innactive for about 20 seconds.
(Except for LEVEL 3 mode.)
When changing parameter, press or key to change the value while the SV digit is
flashing. Press key to shift the digit being changed. After changing, press key to
validate the new value (the original value will be retained if the key is not pressed after
changing any parameter).
Parameter setting for data lock LCK:
1. When LCK=0000, all parameters in all levels can be accessed and changed.
2. When LCK=0001, parameters in LEVEL 1 & LEVEL 2 can be changed, yet the operator
cannot enter LEVEL 3 mode;
3. When LCK=0002, parameters in LEVEL 1 can be changed, and the operator can enter
LEVEL 2 mode, yet its parameters cannot be changed. The value of LCK can be changed.

INSTALLATION
The controller should be installed in a panel cut out as specified. First, remove the mounting
clamp and insert the controller into the panel cut out. Place the unit into the panel cut-out and
slide the mounting clamps from the rear to a firm grip at the panel.
The internal circuitry can be fully removed from the housing without disconnecting any wiring.
Grab firmly the front panel and pull out the circuitry from the housing.
ELECTRICAL CONNECTIONS
All electrical connections are made to the screw terminals at the rear of the controller. They
2 accept wire sizes from 0.5 to 1.5 mm (16 to 22 AWG). The terminals should be tightened to a
torque of 0.4 Nm (3.5 lb in).
The installation must include a power isolating switch or circuit breaker that disconnects all
current carrying conductors. The device should be mounted close to the controller, within easy
reach of the operator and marked as the disconnecting device for the instrument.
Figure 1 shows the electrical terminals of the controller.
