Dwyer 40M - Manual

Programming Device with Configuration Key
The Model 40X-K is not battery powered and requires that the device being
programmed be powered. If a power source is not available, a 40X-PS
power supply must be installed into the port on the edge of the key.
Copying Parameters to Configuration Key
1. Cut off power to the temperature switch
2. Connect the key to the temperature switch
3. Turn on power to the temperature switch or connect the power supply
to the key (LED on key will be green and the temperature switch will flash
“CIn”)
4. Press and hold the SET button on the temperature switch for 4 seconds
(display will flash “St”)
5. Release the SET button on the temperature switch, the press and hold
the SET button again for 4 seconds. (“St” on display will stop flashing
and the LED on the key will turn red)
6. Do not disconnect the key while the LED is red, as it is copying the
parameters
7. After LED on key returns to green, it is okay to disconnect the key. (If
using 40X-PS power supply, disconnect the power supply before
disconnecting the key)
Copying Parameters to Temperature Switch
1. Cut off power to the temperature switch
2. Connect the key to the temperature switch
3. Turn on power to the temperature switch or connect the power supply
to the key (LED on key will be green and the temperature switch will
read “CIn”)
4. Press and hold the button on the configuration key
5. After one second release the button on the key. Parameters will be
copied from the key to the temperature switch. (LED will turn red)
6. The display on the temperature switch will read “PrG” and the LED will
turn green once the temperature switch has been programmed
successfully.
7. Do not disconnect the key while the LED is red, as it is copying the
parameters
8. After LED on key returns to green, it is ok to disconnect the key. (If using
40X-PS power supply, disconnect the power supply before disconnecting
the key)
MAINTENANCE, CLEANING AND REPAIR
After final installation of the unit no routine maintenance is required. Clean
the surface of the display controller with a soft and damp cloth. Never use
abrasive detergents, petrol, alcohol or solvents. A periodic check of the
system calibration is recommended. The Series 40T/40M is not field
serviceable and should be returned if repair is needed (field repair should
not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact
customer service to receive a return goods authorization number before
shipping.

The Series 40T/40M Digital Temperature Switch accepts a variety of
inputs to allow temperature measurements and set points up to 1999°F
(1300°C). Observing the current status of the control is made easier with
the 3-1/2 digit, multi-color LED display that has alarm, defrost and output
symbols. For added versatility, the temperature units can be field selected
for °F or °C. For cooling applications, manual defrost mode can be initiated
by pushing a single button. A flashing alarm informs users when the current
temperature exceeds preset limits. When programming multiple units, a
programming key is available to reduce set up time.
INSTALLATION
Note: Unit must be mounted away from vibration, impacts, water and
corrosive gases.
• Cut hole in panel 71 x 29 mm (2.80 x 1.14 in)
• Apply silicone around the perimeter of the hole to prevent leakage
• Insert unit into hole from the front side of the panel
• Slide the mounting bracket securely against the panel from the rear of
the unit
• Wiring diagram is displayed on top of the control

In order to change the parameter values, follow the procedure below:
• Press UP ARROW and DOWN ARROW simultaneously for four seconds
until PA is displayed
• Press SET
• Use UP ARROW or DOWN ARROW to adjust value to -19
• Press SET
• Press UP ARROW and DOWN ARROW simultaneously for four seconds
until SP is displayed
• Use UP ARROW or DOWN ARROW to cycle through parameters
• Press SET to view value of parameter
• Use UP ARROW or DOWN ARROW to adjust value of parameter
• Press SET to store value
• Press UP ARROW and DOWN ARROW simultaneously for four seconds
to exit menu
