Visualisation Of Electric Network Parameters; Load Control Function And Indications - Gewiss CHORUS P-Comfort GWA9916 Programmierhandbuch

Visualisation of electric network parameters

For information purposes only, information about the electric network parameters is available. To display
this data, starting from the instantaneous power screen, press the
seconds until the first desired parameter is displayed. The parameters available are:
1. Current, expressed in amperes (8.3 A in the example)
2. Voltage, expressed in volts (240 V in the example)
3. Power factor (cosφ, 0.8 in the example)
4. Frequency, expressed in hertz (50 Hz in the example)
Use the and button keys to move between the various displays.
If you press the "SET" button key or after about 60 seconds of inactivity on the device, the absorbed
power screen is displayed.

Load control function and indications

The load control function allows the activation/deactivation of up to 10 KNX devices (10 loads) to be
managed to prevent the tripping of the electric counter if the contracted power is exceeded. By
monitoring the active power on the system, on the basis of the power threshold values, the device
generates the gradual tripping of the loads until the set threshold value is reached.
To activate/deactivate the load control function:
1. Go to the instantaneous power page
2. Press the "SET" button key
3. Press the "SET" button key again to switch from OFF to ON status and vice versa
depending on whether you wish to activate or deactivate the load control function
4. Wait 3 seconds
5. The device returns to the instantaneous power screen
Selecting "thr On" activates the load control function. Selecting "thr OFF" deactivates the load control
function.
When the function is active, the
disconnected load. When the function is active, the device starts to monitor the instantaneous active
power measured, and if the power exceeds the "power threshold + hysteresis" value the device activates
the buzzer and starts the countdown of the duration before load disconnection is tripped. 10 seconds
before the duration expires and the start of the tripping phase, the buzzer frequency increases; at the
end of the countdown, the device makes a long beep and begins disconnecting the loads according to
the set logic. The disconnection ends when the power value reaches the set threshold. Once this
threshold has been reached, the device starts to evaluate load reconnection.
