2.18 kWh and kVArh Display Range The kWh and kVArh display range is limited to 9999999. If the unit is allowed to increment beyond this value the count will either wrap back to zero (if the 1560/1580 transducer is set to 7 digit mode) or continue to be updated in the 1560/1580 transducer but the display will change to seven bars.
19 Integra 1540, 1000, 0640, 0440, 0340, 0240 Issue 1 04/03 3.2 Number Entry Procedure When setting up the unit, many screens require the setting up of a number, usually on the middle row of digits. In particular, on entry to the setting up section, a password must be entered.
Use the key to set the fourth digit to the required value. Press the >> key to confirm your selection. If the unit accepts your entry, the Confirmation screen will appear. If the unit does not accept your entry, e.g. an incorrect password, a rejection screen will appear, with dashes on the bottom line.
3.3 Access To access the Set-up screens, press the and >> keys simultaneously for five seconds, until the Password Introduction screen appears. Password protection can be enabled to prevent unauthorised access to Set-up screens. Password protection is not normally enabled when a product is shipped.
Enter the four-digit password using the method described in Section 3.2 Number Entry Procedure. On pressing >> to confirm the last digit, the Confirmation screen will appear, provided the password is correct. From the Password Confirmation screen, there is the option of changing the password, as described in Section 3.
3.4 Changing the Password The option to change the password is only available from the Password Confirmation screen immediately after the user has entered the existing password, if applicable. Press to start changing the password. The password screen for the first digit will appear, with the old password on the bottom line.
3.5 Full Scale Current This parameter is the value of nominal Full Scale Currents that will be displayed as the Line Currents. This screen enables the user to display the Line Currents inclusive of any transformer ratios. The values displayed represent the current in amps.
To set up the PT primary, proceed as follows: To accept the currently displayed value, press >>. The screen will move on to the next Set-up screen (Section 3.
3.7 Potential Transformer Secondary Value In Model 1000 and 1540 combined, the PT Secondary Value is factory set, as marked on the barrel. The PT Secondary Value is user programmable on the 1540 and Integra 1560 two part.
Press >> to accept the displayed value. Depending on the model, this may take you out of the Set-up screens and back to the last selected Display screen. Press to return to the Decimal Point screen. The secondary value may only be set to values within the range defined by the factory voltage build option.
3.9 Resets The following screens allow resetting of the Energy and Demand readings individually or altogether. Resetting the cumulative Energy (h) resets both Active and Reactive Energy.
Press to return to the Reset screen. Press >> to reset the selected reading(s). The next screen will appear. 3.10 Pulsed Output, Pulse Duration This applies to the Relay Pulsed Output option only. Units with this option provide pulses to indicate power consumption (kWh).
3.11 Pulse Rate This applies to the Relay Pulsed Output option only. Units with this option provide pulses to indicate power consumption (kWh). This screen allows setting of the kWh pulse rate divisor. On a two part DIS 1540/Integra 1560, this screen will set the pulse rate for the kvarh pulse relay (where fitted) also.
3.12 RS485 Baud Rate Use this screen to set the Baud Rate of the RS485 Modbus/JC NII port. The values displayed are in kbaud. Where the transducer unit may be separate from the display unit, the transducer has two Modbus ports, at least one of which may be used for communicating with a display.
3.13 RS485 Parity Selection This screen allows setting of the parity and number of stop bits of the RS485 Modbus/JC II port. Where the transducer unit is separate from the display unit, the transducer has two Modbus ports, one of which may be used for communicating with a display.
3.14 RS485 Modbus Address This screen allows setting of the Modbus/JC NII device address for the instrument. Where the transducer unit is separate from the display unit, the transducer has two RS485 ports, one of which may be used for communicating with a display.
3.15 Analogue Output Set Up This is an option on Models 1540 that have separate (1560 or 1580) transducers. 3.15.1 Introduction This applies to the analogue output option only, allowing the parameter to be selected, and the upper and lower limits adjusted, for either one or two channels.
3.15.2 Analogue Output Scaling Example In this example, the Integra has an output current range of 0 to 10mA and it is required that this output range represents a reading range of 95 to 135V. 3.15.2.1 Reading (A1r or A2r) The measured electrical parameter that the analogue output will represent.
3.15.2.6 Output Bottom (A1ob or A2ob) This is the value of output that will be reached when the measured electrical parameter is at the reading bottom value. Example: 0mA 3.15.2.7 Summary In the above example, the analogue output will be 0 mA when the average voltage is 95 volts, 5 mA at 115 volts and 10 mA at 135 volts.
When setting up the analogue output for a power factor reading, the Reading Top value must be in one of the left-hand quadrants and the Reading Bottom value must be in one of the right- hand quadrants. Hence, if the Reading Top value is set to –0.5, this will be a power factor of 0.
In the example above, the unit has an analogue output range of 0 to 1 mA, all power is imported and the load is inductive. The 1 mA Output range covers a reading power factor range of 0.6, from 0.9 capacitive to 0.5 inductive. The capacitive overlap is provided in case of over- compensation of power factor.
In this example, the unit is set to represent the full range of inductive and capacitive loads on imported and exported power. The unit has an analogue output range of –1 to +1 mA. Both Reading Top and Reading Bottom are set to –1 power factor. 3.
