8.2.2. Voltage sensing inputs
The ATyS t includes dual single phase and three phase voltage sensing (terminals 103 - 106 and 203 - 206)
designed to monitor 1Phase (L-N) supplies of up to 332Vac and 3 phase (L-L) of up to 575/600Vac.
The ATyS t is designed to handle single phase, three phase with neutral as well as three phase without neutral
networks. Simply define the correct configuration of single or three phase and with or without neutral using dip
switches (positions A/B, C/D) on the front of the ATS controller.
Sensing connections are usually tapped directly off the ATy
S t power terminals using the AT
yS sensing kit available
as an accessory. Sensing kits are available with the neutral on the left or neutral on the right to match the network
configuration where the AT
yS will be operating. Refer to the ATyS accessory section for more details.
Sensing values measured will have a direct influence on determining the availability of the main and the alternative
supplies as well as the ATy
S t automation.
The parameters monitored through sensing are the following:
•
Phase rotation / imbalance (3 phase networks)
Phase imbalance in the ATy
S t is relative to the nominal voltage configured with auto conf together with the
hysteresis set in position G/H (10/20%) with dip switch 4.
• Frequency within set limits
This will depend on the nominal frequency configured using auto conf together with the hysteresis set in position
G/H (5/10%) with dip switch 4.
• Loss of Neutral
When used on three phase + neutral applications (configured with dip switch 1 set on position A and dip switch
2 set on position C, the loss of neutral will be detected for most unbalanced loads. Detection will be done when
the load is on.
• Loss of the main or alternative supply
.
Loss of supply depends on the nominal voltage and frequency configured using auto conf together with
the hysteresis set in position G/H (10/20% for ΔU and 5/10% for ΔF) with dip switch 4. The supply will be
considered as failed after the failure timer (set through potentiometer FT on the ATS controller) has elapsed. The
FT setting is adjustable from 0 – 60 seconds.
• Return of main and / or alternative supply.
Return of supply depends on the nominal voltage and frequency configured using auto conf together with
the hysteresis set in position G/H (10/20% for ΔU and 5/10% for ΔF) with dip switch 4. The supply will be
considered as returned after the return timer (set through potentiometer RT on the ATS controller) has elapsed.
The RT setting is adjustable from 0 – 60 minutes.
Measurement accuracy: Frequency: 0.1% - Voltage: 1%
