4. Tatūnga me te Tāuta
Installation of the BFT SB-BAT P125002 kit is designed to be straightforward. However, it is recommended that installation be performed by a qualified technician to ensure safety and correct operation. Always disconnect main power to the gate operator before beginning installation.
4.1. Whakatupato Haumaru
- Momotu Mana: Always turn off the main power supply to the gate operator before installation or maintenance.
- Utauta Tika: Use appropriate tools for electrical connections and mounting.
- Waea waea: Ensure all wiring connections are secure and correctly polarized.
- Taiao: Install the kit in a dry, protected location, away from direct weather exposure.
4.2. Nga Waahi Whakataunga (Nga Aratohu Atoa)
- Mount the Battery Holder: Secure the battery holder/mounting base within the gate operator's control box or an appropriate enclosure using the provided mounting brackets and fasteners. Ensure it is stable and accessible.
- Kōkuhu Pūhiko: Place the two 12V 1.2Ah batteries into the battery holder.
- Tūhono Pūhiko: Connect the batteries in series to achieve 24V DC, following the wiring diagram provided with your specific gate operator or the kit's smart charger board. Ensure correct polarity.
- Connect Smart Charger Board: Integrate the smart charger board into the gate operator's control unit. Refer to your gate operator's manual for the specific connection points for the battery backup system.
- Waea Haumaru: Route and secure all wiring to prevent pinching or damage.
- Whakaora i te Mana: Once all connections are verified and secure, restore main power to the gate operator. The smart charger board will begin charging the batteries.
- Pūnaha Whakamātautau: Perform a power outage simulation to verify the battery backup system activates correctly and powers the gate operator.
5. Nga Tohutohu Whakahaere
The BFT SB-BAT P125002 operates automatically once installed correctly.
5.1. Normal Operation (Power On)
When main power is supplied to the gate operator, the smart charger board within the SB-BAT kit continuously monitors the battery charge level. It will charge the batteries as needed to maintain them at full capacity.
5.2. Mana Outage Operation (Power Off)
Ina he mana outage, the smart charger board automatically detects the loss of main power and switches the gate operator to battery power. The gate operator will then function normally using the stored energy in the batteries. The duration of operation on battery power depends on the frequency of gate usage and the charge level of the batteries.
6. Tiaki
Regular maintenance ensures the longevity and reliability of your battery backup system.
6.1. Battery Recharging
I muri i te mana outage, once main power is restored, the smart charger board will automatically begin recharging the batteries. A full recharge typically takes 12 ki te 14 haora. It is important to allow sufficient time for batteries to fully recharge after use.
6.2. Fuse Check
Kei roto i te punaha he 20He whakakorikori for protection. If the battery backup system fails to operate or charge, inspect the fuse for continuity. Replace with a fuse of the exact same rating if necessary. Always disconnect power before checking or replacing fuses.
6.3. Te Ora Pūhiko me te Whakakapinga
Batteries have a finite lifespan. Periodically test the system by simulating a power outage to ensure batteries hold a charge and can power the gate operator. If performance degrades significantly, consider replacing the batteries. Use only recommended replacement batteries (2x 12V 1.2Ah sealed lead-acid).
7. Te Raru
If your BFT SB-BAT P125002 battery backup system is not functioning as expected, consider the following:
- No Power During Outage:
- Manatokohia he haumaru, he tika hoki nga hononga waea.
- Check the 20A fuse.
- Ensure batteries are fully charged. If recently discharged, allow 12-14 hours for recharging.
- Whakamatautau puhiko voltage. If below 20.4V (exhausted battery protection threshold), batteries may need replacement.
- Nga Pikohiko Kaore i te Whakataki:
- Confirm main power supply to the gate operator is active.
- Check all connections to the smart charger board.
- Inspect the 20A fuse.
- Reduced Operation Time:
- Batteries may be aging and losing capacity. Consider replacement.
- Ensure batteries are fully charged before testing.
For persistent issues, contact BFT technical support or a qualified service technician.
