Platinum RTD Inputs

The inputs provided for these sensors are terminals All A&B through Al8 A&B. The inputs are two+vire, twisted pair with shield.

Inputs are not polarized; terminate one of the wires to terminal A and the other wire to terminal B. Terminate the shield to cabinet ground closest to the entry point of the wire into the enclosure (cut off all additional wire). Cut and tape the shield at the sensor end to prevent it from coming in contact with junction box or other conductors. Refer below for wiring and setup information.

Wirino Lenath Error

The elements SCALE and OFSET are used to convert the resistance reading to the proper engineering units. These elements also provide a method of calibrating the sensor’s displayed value to any desired value, thus correcting the system for any errors that may result from wire length or other variables.

Wiring length error can be eliminated by modifying the element OFSET. Because the resistance of the wire will be measured along with that of the sensor element, an error may result.

AWG 24 wire has a resistance of 17 ohms per thousand feet. If 50 feet of cable are used in a run, the resistance will be : 50’ x 2 (wires) x 17 ohms/l 000’ = 1.7 ohms.

The sensor has a sensitivity of approximately 2.2 ohms per degree. This 1.7-ohm error will result in a reading that is approximately .77 higher than the sensor would read if the wiring error were not present. To eliminate this error using the element OFSET, simply subtract .77 from the value given in the table for OFSET.

O-1 1Vdc Analog Inputs

When configured as a voltage sensor input, the universal analog input measures between 0 and 11 Vdc. The input terminals provided for this range of voltage are terminals All-A18. Terminate the positive wire to terminal A and the negative wire to terminal B. Terminal B is tied directly to ground on the circuit board, so all voltages must be referenced to ground. Differential and negative voltages must not be measured. See Figure 5 below for wiring and setup information.

The table below illustrates the numbering scheme and software assignments of the eight &l 1 Vdc analog inputs. When making these assignments, the first entry is the option slot number on the connected MSC-MPC controller and the second entry is the number of the analog input being used.

Calculating SCALE and OFSET Using MOCALC

MOCALC comes standard with the DOS Configuration Tool and is used to determine the proper values for SCALE and OFSET when provided with the desired values to be displayed from given input parameters. MOCALC is typically used to calibrate the display in engineering units in accordance with measurements taken. In some cases it can be used to correct for tolerance errors in input or output readings.

To use MOCALC, several parameters must be measured prior to running the program. First, the physical property to be measured or controlled is sampled near the high end of its scale and the corresponding bit value is recorded. Then another reading is taken with the property at the low end of its scale and the bit value displayed by the system is again recorded. Once this information is determined, the MOCALC program is able to calculate the appropriate values for SCALE and OFSET. Note that the characteristics of the variable must be linear to use MOCALC.

The sample calculations below are for a Belimo SM24 Actuator with the P500 feedback option that will be used to control a valve from 0 to 100 percent open.

For the point to be calibrated, set OFSET = 0 and SCALE = 4096.

With the feedback wired, drive the actuator/valve fully open (100%). Record the measured bit value displayed by the system for this point. This is the bit high value”. Next, drive the actuator/valve fully closed (0%). Record the measured bit value again. This is the “bit low value.”

1. From the CUCM directory, type MOCALC and press ENTER.

2. At the Enter Number prompt, type 1 to select Formulas for Scale and Ofset.

3. At the Enter Number prompt, type 6 to select Formulas for Bit High...Bit Low.

The program prompts you for the device range high and range low values. These values are the range of the points display, which in this case is from 0 to 100 percent (open). You will also need to enter the recorded bit values when’the actuator was driven to these two positions. MOCALC will then compute the proper SCALE and OFSET for the point to display linearly across the actuator’s travel range.

Please Enter Device Range High Value Number: 100

Please Enter Device Range Low Value Number: 0

Please Enter Recorded BIT HIGH Value Number: 3298

Please Enter Recorded BIT LOW Value Number: 517 SCALE: 147.28 OFSET: -18.59

In the example above, the desired display range for the actuator is 0 to 100 (percent open). The corresponding low and high bit values were recorded as 517 and 3298, respectively. MOCALC determined SCALE to be 147.28 and OFSET to be -18.59.

The formulas used by MOCALC are as follows:

SCALE = 4096 l (RANHI - RANLO) (BITHI - BITLO)

OFSET = RANLO (SCALE l BITLO) 4096

You are now ready to execute the MOCALC program.
