Frequently Asked Questions - 5M14X1 Daytronic

How do I connect the power supply to the Daytronic 5M14X1?

Connect the AC power cord to the terminal block labeled POWER (100-240 V AC, 50/60 Hz). Ensure the device is switched off before connecting.

Can I use the 5M14X1 with a 4-20 mA sensor?

Yes, the device accepts standard analog inputs including 4-20 mA. Configure the input type via the setup menu (see manual section 3.2).

How do I set an alarm threshold?

Press the MENU button, navigate to ALARM, then set the desired high/low limits. The alarm output will activate when the reading crosses the threshold.

What should I do if the display shows 'OVER'?

'OVER' indicates the input signal exceeds the configured range. Check the sensor wiring and verify the input scaling settings. Reduce the input signal or adjust the range.

How can I reset the device to factory defaults?

While holding the ENTER key, power on the device. Continue holding until 'FACTORY' appears on the display. Release to reset all settings.

Can I log data from the 5M14X1 to a PC?

Yes, use the optional RS-232/485 serial interface. Connect to a PC via a USB-serial adapter and use Daytronic's DataView software or a terminal program.

How do I calibrate the unit?

Calibration requires a known reference signal. Enter the calibration mode via the menu (password required). Apply the reference signal and adjust offset/gain as prompted.

What is the maximum input voltage?

For voltage inputs, the maximum is ±10 V DC. For current inputs, 0-20 mA or 4-20 mA only. Exceeding these may damage the input circuitry.

Does the device support thermocouple types?

Yes, it supports J, K, T, E, R, S, and B thermocouples. Select the thermocouple type in the input configuration menu (section 4.1 of the manual).

How do I clean the front panel?

Use a soft, dry cloth. For stubborn dirt, slightly dampen with water. Do not use abrasive cleaners or solvents. Avoid getting liquid inside the device.

USER MANUAL 5M14X1 Daytronic

The Model 5M14(V) is a precision conditioner designed for TC-based temperature measurements requiring high input isolation. With built-in reference-junction compensation, it accepts up to four independent temperature signals from Types E, J, K, N, R, S, and T Thermocouples. All four thermocouple inputs must be of the same type. Sensors may be grounded or ungrounded, in any desired mix. An amplifier-per-channel design with chopper stabilization and active low-pass filtering allows highly responsive, amplified analog signals with or without linearization correction.

For the Model 5M14, the analog output signal is 5 Vdc and the 5M14V is 10 Vdc. These are nominal full scale voltages since the Module is based on a millivolt per degree C value. All setup of the module is accomplished via the front panel configuration switch settings - polarity over-range, TC type, filter setting, extended gain, and linearized or non-linearized output.

Access switch settings via the front panel of the 5M14 by gently pulling the clear plastic cover (from the bottom side) so the cover rotates open from the top. Use a small tool or finger to place the switches to the left or right position as you face the front of the module. This process can be done with or without power to the unit. Once completed, return the cover to the original position.

Open Thermocouple Detection (OTC)

Can be set per individual TC input to saturate the analog output signal full-scale positive or negative.

Note: when this condition exists the analog output can be as much as 12 Vdc. When an OTC condition occurs, the yellow LED indicator on the front of the module will illuminate.

2 TRANSDUCER CONNECTIONS

The Model 5M14(V) I/O CONNECTIONS are via non-removable screw terminals which will accept wire sizes from AWG 12 to 26. NOTE: unused thermocouple inputs should have their individual channels + and - terminals shorted together to prevent over-range LED light indication. Thermocouple wire should be directly attached to its corresponding screw terminals - never solder or use copper wire extensions which will cause cold junction compensation errors. Table 2 denotes screw terminal assignments.

3 CALIBRATION

The Model 5M14(V) does not require field calibration. Front panel selector switches, as shown below, will enable the correct linearization and cold junction temperature compensation to the thermocouple connected to the unit. All four thermocouples will be conditioned and linearized for the thermocouple type selected. Note: Depending on the switch selection, the conditioned output of the thermocouple signal(s) will be -1) Normal gain through-out the thermocouple's temperature specification to NIST tables. 2) Extended gain if the user desires amplification in a restricted temperature range. 3) Non-linearized which enables the Cold Junction Compensation and gain amplification only. In this mode it is expected that the external readout device connected to the 5M14(V) will perform the correct linearization operation for the application and connected thermocouple sensor(s).
