TERMINAL LAYOUT AND WIRING

Thermocouple wiring:

When wiring a thermocouple input, the compensation wire should be qualified and directly connect to the corresponding terminals in correct direction. When M1 module is installed in J1 socket, a Cu50 resistor can be connected between terminal 17 and 20 to compensate the cold junction; short connection between terminal 17 and 20 can realize ice-point compensation.

Two-wire RTD wiring:

RTD can select two-wire or three-wire method by B of “AF” parameter. Two-wire method enables to input two channel signals in one module, but user has to measure and calculate the resistance of the wire. To apply two-wire method, the J2 module should be installed and the resistance of every wire should be less than 2ohm.

HM-104M can measure the lead wire resistance of two-wire method and save it to parameter “Sc”. However, the lead wire resistance changes as the temperature changes. If the lead wires has the same ambient temperature as that of the instrument and no other resistor series connects to the lead wire, the indicators can compensate the resistance change by measuring the ambient temperature (compensation coefficient is 0.004/°C); Otherwise, two-wire method is not recommended.

Three-wire RTD wiring:

Three-wire method is a traditional wiring method requiring that the resistance of the three wires be equal. One "J0" module supports 1 three-wire RTD. Three-wire method provides higher measurement accuracy.

FRONT PANEL AND OPERATIONS

Basal operation description

3. Alarm display:

The lower display window shows channel number. If high or low alarm occurs, the first digit from the left of lower display window will show “H” or “L”, and flickers, and if over range occurs (for example, wire broken for thermocouple input), the upper display window will show high or low limit valve, and the lower display window flickers.

If only 2 input channels configured, then the upper and lower display window will show the input values of channel 1 and 2 respectively. When over range occurs, the corresponding display window will flickers.

Lead wire resistance compensation for 2-wire RTD input:

Offset value (parameter “Sc”) need to be set to counteract lead wire resistance for 2-wire type RTD like Pt100 or Cu50. This offset value can be set automatically by the following procedures:

1. Short connect 2 wiring terminals on the RTD sensor side

2. Set parameter “Loc” to 808, and then pressuntil “A” appears on the first digit of lower display window.

3. Wait until “A” disappears, and then removes the short wire, and set “Loc” to 0 or 1.

4. Now, the instrument comes back to normal measurement display mode, and the setting of parameter “Sc” is finished.

The unit of Sc is 1/20000 of the scare of the corresponding RTD. At 0°C, the total resistance of the two lead wire of Pt100 or 0~400ohm should be less than 4ohm, and that of Cu50 should be less than 2ohm. Otherwise, wire resistant compensation will not function. The smaller the resistance of the lead wire can provide more accurate measurement.

4. DIN rail mounted type

DIN mounted type (dimension E5) has no display window. It can input analog signals or input/output on-off signals for host computer or PLC, and it can also work as a two-channel programmable re-transmitter.

E5 dimension instrument has one LED indication light. When the instrument is communicating with the host computer, the light flashes with light on time different to light off time. When the instrument hasn’t received signal from the host computer for 6 seconds, the indication light should flash with the same light on time and light off time.

It means:

a)That the on-off period is as long as 1.6 second means no communication and no alarm (it can be treated as normal);

b)The light flashing with period 0.6 second means no communication and general error occurs.

c)The light quickly flashing with period 0.3 second means no communication and severe error such as input over range occurs.

d)The light keeping off means the instrument power off or damaged; the light keep on (longer than 8 seconds) means the instrument power on but damaged.

The parameters of E5 dimension instrument can be set by connecting external display to the 1394 socket.

Note: The 1394 socket of the instrument only supports HM external display.

The instrument can be connecting PC or PLC to monitoring or capture the data. We can provide the FREE protocol for user or order our monitoring software-AIDCS. Please contact HM Sales Dept. for more detail.

5. Dry Bulb, Wet Bulb Humidity Measurement

By connecting 2 units of 3 wires PT100 for input, is can become the dry bulb, wet bulb humidity measurement.

1. Install J0 module (RTD input module) in M1 and M2 slot. Set Sn1=22, Sn2=42.

2. Atmospheric pressure and wind speed defined by parameter “Po” and “SPEd”

3. Tuning humidity first with the bulb wrapped in wet muslin, after the reading stabled

4. Adjust parameter Sc2 to make the reading reach 100%,

5. Can remove the wet muslin after the adjustment.

6. Set parameter dIP1=1, dIP2=0, resolution will 0.1°C and 1%RH
