SOLAR MODE & PARAMETERS
Please read this section to understand the terminology and parameters before proceeding with any programming.
Solar related parameters
This manual supplement includes only the solar related parameters. For all other parameters refer to the ZENER 8000 manual.
The setup guide in Appendix A will guide you through the parameters and commissioning process for the different applications.
These parameters will be programmed by loading the ‘Application’ and accessed if required in the ‘Application Menu’
E07 SOLAR SUPPLY:
Menu ID.
E070 RUN MODE:
A logic input to select the solar operation and its internal ‘tracking’ controller.
E071 RESTART DC:
The DC voltage from the solar panels that is required to attempt a restart of the motor (pump). An
Irradiance sensor (if fitted) can also be used to restart if assigned to a control input or function.
E072 RESTART DELAY :
The time that the DC bus voltage from the solar panels must be above the restart DC voltage before
a restart commences.
E073 RADIANCE LO
When an irradiance sensor is used, this can be selected as a digital source to trigger a stop (or other
purpose).
E074 RADIANCE HI
When an irradiance sensor is used, this can be selected as a digital source to trigger a start (or other
purpose).
E075 VMP VOLTS
Array volts at Maximum Power, this is obtained from the PV data sheet x number of series panels in
a string. Tracking activates if voltage from the PV’s (solar panels) falls below this threshold.
E076 Display Var
This allows the selection of either PV-A (PID such as Pressure) or PV-B(Solar W/m2) variable.
E077 LO SOLAR TIME
When the speed decreases less than the ‘C01 MINIMUM SPEED’ for this time period, low solar state
is active. This is generally used to stop the ECODRIVE or can also be assigned to a relay to switch on
an AC Power supply.
E078 SFC time
Relevant for dual or aux supply applications only to detect a conflict. When a conflict is detected
the ECODRIVE will run on AC power for the set time period before re-attempting to run with solar
power.
E079 SFC Ext Sel
A logic input to force an ‘SFC’ state from an external or other source.
Solar Function & Modes
The ECODRIVE when operating in Solar Mode will be in one of the following modes or states:
1.
“OFF”
Solar Operation OFF, Standard VSD operation.
2.
“LO SOLAR”
The output frequency (speed) is less than ‘C01 Minimum speed’ due to tracking and ‘E077 LO SOLAR
TIME’ has lapsed.
OR
If an irradiance sensor is fitted, by the digital source ‘E073 LO Radiance’ and ‘E077 LO SOLAR TIME’ has
lapsed.
3.
“SOLAR GOOD”
The DC bus voltage is greater than the ‘E07 Restart DC’ for the ‘E072 Restart delay’.
OR
If an irradiance sensor is fitted, by the digital source ‘E074 HI Radiance’ for the ‘E072 RESTART DELAY’.
