Figure 1: Finder Series 22 Modular Contactor (Model 22.32.0.230.4320 shown in image, but the product is 22.32.0.024.1320). The image displays the device with its coil terminals A1 and A2, and contact terminals 1, 2, 3, 4. Key specifications like "EN 61095", "25A 440V AC", and "AC 7a" are visible, along with the "Finder" brand logo and "Made in EU" marking. The coil voltage for the depicted unit is 230V AC/DC, while the product covered by this manual uses a 24V AC/DC coil.

4. Setup and Installation

4.1 Mounting

The modular contactor is designed for mounting on a standard 35mm DIN rail. Ensure the rail is securely fastened within an appropriate enclosure. Snap the contactor onto the DIN rail by aligning the top edge and pressing firmly until it clicks into place.

4.2 Wiring Connections

Refer to the wiring diagram provided with the product or on the device itself for specific connection points. Ensure all connections are tight and secure to prevent loose contacts and overheating.

Coil Connections (A1, A2): Connect the 24V AC/DC control voltage to terminals A1 and A2. Observe polarity if using DC, though many coils are non-polar.
Main Contact Connections (1, 2, 3, 4): Connect the load circuit to the main power contacts. For a DPST-NO (Double Pole Single Throw - Normally Open) configuration, terminals 1 and 3 are typically inputs, and 2 and 4 are outputs. When the coil is energized, contacts between 1-2 and 3-4 will close.

Always verify that the power supply is disconnected before making any wiring connections.

5. Operation

The Finder Series 22 Modular Contactor operates by energizing its coil. When the specified 24V AC/DC control voltage is applied to terminals A1 and A2, the electromagnetic coil activates, causing the normally open (NO) main contacts to close. This allows current to flow through the connected load.

Energizing the Coil: Apply 24V AC/DC to A1 and A2.
Contact Closure: The main contacts (1-2 and 3-4) will close, completing the power circuit to the load.
De-energizing the Coil: Remove the 24V AC/DC control voltage from A1 and A2.
Contact Opening: The main contacts will return to their normally open state, interrupting the power circuit to the load.
Indicators: If equipped, the LED indicator will illuminate when the coil is energized, and the mechanical indicator will show the contact status.

6. Maintenance

Regular inspection and maintenance can extend the lifespan of your modular contactor. Always disconnect power before performing any maintenance.

Visual Inspection: Periodically check for any signs of physical damage, discoloration, or loose connections.
Cleaning: Keep the contactor free from dust and debris. Use a dry, soft cloth for cleaning. Do not use solvents or abrasive cleaners.
Terminal Tightness: Ensure all terminal screws remain tight to prevent overheating due to poor contact.

7. Troubleshooting

Problem	Possible Cause	Solution
Contactor does not engage when control voltage is applied.	No control voltage to A1/A2. Incorrect control voltage (not 24V AC/DC). Loose wiring connection to A1/A2. Damaged coil.	Check control circuit for power. Verify control voltage is 24V AC/DC. Tighten A1/A2 connections. Replace contactor if coil is damaged.
Load does not receive power when contactor engages.	No power to main contacts (1, 3). Loose wiring connection to main contacts. Damaged main contacts. Overload condition.	Check main power supply. Tighten main contact connections. Replace contactor. Investigate and resolve overload.
Contactor hums loudly.	Loose components. Incorrect voltage.	Ensure proper mounting and tightness. Verify correct 24V AC/DC control voltage.
