User Guide Revision 1.12 7. HVAC Specific Feature Setup (Menu 8) The drive has several features inbuilt into the drive standard operating software that are specific to HVAC applications. The majority of parameters used in enabling and configuring these functions are contained within menu 8 (See section 11.7). This section is an explanation of the purpose and operation of each of these functions and guidelines on how each one can be configured. 7.1.
User Guide Revision 1.12 Set Basic parameters P1-01 to P1-10. Energy Optimiser P1-06 must remain disabled.
User Guide Revision 1.12 When the system is enabled the master drive will check the run time clocks for all drives in the network which are stored and maintained within menu 0 of the master drive. The first available drive with the lowest run time is automatically run first. At a predefined level additional drives / pumps are brought on-line in sequence to assist the running pumps.

The timer for the next service interval starts from the point at which the previous indication was reset.
User Guide Revision 1.12 A detection tolerance for the Load Profile Monitoring Function is set within parameter P8-07. Parameter P8-07 (Load Profile Monitoring Function Bandwidth) is set as a current (amps) value and is then applied to the standard operating profile stored within the drive to allow for acceptable variations in the motor current measurement. The value entered is applied symmetrically to the nominal current value so totally bandwidth is 2 x P8-07.
User Guide Revision 1.12 The Pump Cleaning cycle is defined by setting two segment speeds, a ramp time (used for acceleration and deceleration), and a segment time in the following parameters: Parameter Number P2-05 P2-06 P8-04 P8-05 Description Clean Speed 1 Clean Speed 2 Pump Cleaning Function Time Interval Pump Cleaning Function Ramp Time If either of the two Pump Cleaning Speeds are set to zero then that segment of the cleaning cycle is disabled.
User Guide Revision 1.12 Operational Overview: The time period to trigger the pump Stir function is entered into parameter P8-01 (Stir Function Integral Timer). When the drive enters into standby mode (see PID control, section 8) an internal timer is started. When the timer exceeds the user defined time limit set in P8-01 a preset motion profile is activated. When function execution is completed the drive returns immediately to standby mode.
User Guide Revision 1.12 The main selector switch selects between the following modes. System Off : Drive is powered off; Bypass contactor is off Bypass Control : Drive is powered off; Bypass contactor is on, motor running from bypass supply Drive Control : Drive is powered on; Bypass or Drive Output contactor selection is controlled by the drive When the Main Selector Switch is set to Drive Control, the drive input contactor is switched in such that the drive will power up.
User Guide Revision 1.12 Bypass Mode on Fault is enabled by setting parameter P8-11=1 (enabled). Once enabled the drive will switch to bypass mode in the event of a trip or fault occurring on the drive. When a trip occurs the drive will immediately open the drive output contactor (drive output already disabled due to trip), wait a time (defined by P8-13) and then close the bypass contactor.
User Guide Revision 1.12 P9-32: Fire Mode input source can be set via P9-32 to an available digital input. Advanced level security (default P1-14 = 201) is required to access menu 9 parameters The fire mode function is enabled once an input is assigned to activate fire mode. The logic selection for the fire mode input is configured through parameter P8-09 – Fire Mode Logic Select. It can be set to open active (0) or close active (1).
User Guide Revision 1.12 Set parameter P9-32 to an available digital input value. Note, P1-13 must be set to 0. Any other digital inputs required must also be configured through menu 9. If required, set either P2-15 or P2-18 = 9 to configure output relay 1 or output relay 2 to indicate fire mode active. 7.9.
User Guide Revision 1.12 The function uses the Boost Voltage on the drive reaching zero speed in order to create a current and maintain an appropriate temperature within the motor. The drive Standby Mode must be disabled so that the drive output is not automatically put into Standby following a period of operation with zero speed reference. The level of DC Injection Voltage applied to the motor is set in parameter P1-11 (V/F Boost Voltage).
User Guide Revision 1.12 8. PID Control Applications 8.1. Overview The PID Controller is a mathematical function designed to automate adjustments within a system and to eliminate the need for the machine operator to continuously pay attention to machine operation and to make manual adjustments.
User Guide Revision 1.12 8.2.3. PID Operating Mode Selection For default operation the drive response to an increase in feedback signal is to decrease motor speed and vice versa to adjust the feedback signal back to the set-point. This is referred to as ‘Direct Mode’ PID control. For example when pressure increases in a pumping system and the feedback signal increases then the drive response is to slow the pump to reduce the pressure.
User Guide Revision 1.12 point). For dynamic systems which respond quickly, the value will need to be shorter. Slow response systems, such as temperature control applications will require a correspondingly longer time setting. P3-03 Differential Time Constant: Range 0.00 to 1.00, Default 0.00 The differential time constant is also a time based function, this time modifying the PID output based on changes in the Set-point. In most applications, leaving the setting of P3-03 at zero will give good results.
User Guide Revision 1.12 The execution time for both the sleep and wake boost functions (P6-11 and P6-12) include the time taken to accelerate to the boost speed (P207 and P2-08) but not the time to accelerate or decelerate once the boost function ends. This is shown in the timing diagrams. When boost on sleep in activated the drive will automatically run the boost on sleep function whenever the drive is stopped / disabled.
User Guide Revision 1.12 8.4. PID Pipe Prime (Fill) Mode with Pipe Break Detection. Pump prime mode allows starting of the pump in a safely controlled manner, to ensure consistent filling and pressurisation of pipe work and systems. Low pressure warnings are ignored during priming to allow the system to prime correctly, whilst a failsafe timeout prevents the pump from continuing to run in the event of a failure to prime.
