2. Nga korero haumaru

WHAKATŪPATO: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel in accordance with all local and national electrical codes.

• Always disconnect power before installing, servicing, or removing the relay.
• Me whakarite te turanga tika kia kore ai e ru te hiko.
• Manatokohia ko te tuku voltage and current ratings match the relay's specifications.
• Kaua e whakahaerehia te relay i roto i ngā taiao e neke atu ana i ngā rohe pāmahana, haumākū rānei kua tohua.
• Avoid exposing the relay to moisture or corrosive substances.

4. Tatūnga me te Tāuta

This pulse relay is designed for panel mounting. Follow these steps for proper installation:

1. Momotu Hiko: Ensure all power to the installation area is disconnected at the main circuit breaker before beginning any work.
2. Whakapiki: Securely mount the relay within an electrical panel using appropriate fasteners. The relay dimensions are approximately 1.26 x 2.17 x 2.76 inches.
3. Hononga Waea:
   • Identify the three terminals on the relay.
   • Connect the control circuit wires to the coil terminals (A1, A2) as indicated on the relay. The coil voltage is 230 Volts AC.
   • Connect the load circuit wires to the contact terminals (1 NO) using the clamp-type connectors. The relay is rated for 10 Amps.
   • Me whakarite kia piri, kia mau nga hononga katoa kia kore ai e wetewete nga hononga me te wera nui.
4. Manatoko: Double-check all wiring against the electrical diagram for your specific application.
5. Whakaora Hiko: Kia oti te whakaurunga me te manatoko, whakahokia te hiko ki te ara iahiko.

5. Nga Tohutohu Whakahaere

The Finder Series 27 pulse relay operates automatically based on the control signals it receives. It is commonly used in applications where a momentary input signal triggers a change in the output state, which then remains until the next momentary input.

• When a pulse is applied to the coil terminals (A1, A2), the internal mechanism latches, changing the state of the 1 NO contact.
• The contact remains in this new state even after the control pulse is removed.
• A subsequent pulse will revert the contact to its original state.
• The relay supports three distinct operational sequences, which are determined by the specific model variant and internal configuration. Refer to your system's wiring diagram for the exact sequence implemented.

6. Tiaki

The Finder Series 27 pulse relay is designed for long-term, reliable operation with minimal maintenance. However, periodic inspection is recommended:

• Tirotiro Ataata: Periodically inspect the relay for any signs of physical damage, discoloration, or loose connections.
• Te horoi: Ki te mea e tika ana, horoia mārire te taha waho o te whakawhiti ki te kakahu maroke, ngohengohe. Kaua e whakamahia he whakarewa, he kaihoroi whakakoi rānei.
• Taki Hononga: Ensure all wiring connections remain tight and secure.
• Nga Tikanga Taiao: Manatokohia kei te noho tonu te taiao whakahaere i roto i nga awhe pāmahana me te makuku.

Tuhipoka: The relay is a sealed unit and is not user-serviceable internally. Do not attempt to open the casing.

7. Te Raru

If the Finder Series 27 pulse relay is not functioning as expected, consider the following troubleshooting steps:

• No Response to Control Signal:
  • Check if power is supplied to the control circuit and the relay coil (A1, A2).
  • Verify that the control signal voltage matches the relay's coil voltage (230V AC).
  • Inspect control circuit wiring for breaks or loose connections.
• Load Not Switching:
  • Ensure the relay is receiving control pulses and its internal mechanism is audibly clicking or visibly changing state (if applicable).
  • Check the load circuit wiring for continuity and secure connections.
  • Verify that the load current does not exceed the relay's 10 Amp whakatauranga.
  • Confirm that the load itself is functional.
• Relay Overheating:
  • Ensure the load current does not exceed the relay's maximum rating.
  • Check for proper ventilation around the relay within the panel.
  • Verify that the ambient temperature is within the specified operating range.

If issues persist after performing these checks, contact a qualified electrician or Finder technical support.
