Setup and Installation

Mounting:

The H3CA-A timer is designed for use with an 11-pin socket, allowing for either panel mounting or DIN rail mounting. Ensure the socket is securely fastened before inserting the timer.

Wiring Instructions:

Refer to the wiring diagram below for proper connection of power, inputs, and outputs. Ensure all connections are secure and insulated.

Figure 2: Wiring diagram for the H3CA-A timer, illustrating connections for Reset, Start, Gate, Check inputs, Power (pins 2 and 10), and SPDT output (pins 8, 9, 11).

1. Power Supply: Connect the universal voltage supply (24-240 VAC/DC) to pins 2 and 10.
2. Control Inputs: Connect Reset, Start, Gate, and Check inputs as required for your application. These inputs are typically connected to a common line.
3. Output: The timer provides a Single Pole Double Throw (SPDT) output. Connect your load to the common (pin 8), normally open (pin 9), and normally closed (pin 11) terminals as per your control requirements.

Operating Instructions

Powering On:

Once wired correctly, apply power to the timer. The LCD display will illuminate, and the timer will enter its default or last-saved operating mode.

Setting Time Ranges:

Use the "Time Unit Selector" buttons to choose the desired time unit (e.g., seconds, minutes, hours). The available ranges are from 0.1 seconds to 9,990 hours.

Setting Time Value:

Use the "Set Time" buttons to adjust the numerical value for the selected time range. The LCD will show the set time.

Selecting Operation Modes:

The H3CA-A offers 8 field-selectable operation modes. These modes determine how the timer functions in response to inputs and how its output behaves. Refer to the product documentation or the label on the device for specific instructions on how to select these modes, as this often involves internal DIP switches or specific button combinations.

• A: ON-delay operation
• B: Flicker operation
• C: Signal ON/OFF-delay operation (1)
• D: Signal OFF-delay operation (1)
• E: Interval operation
• F: One-shot and flicker operation
• G: Signal ON/OFF-delay operation (2)
• H: Signal OFF-delay operation (2)

LCD Display Interpretation:

The LCD provides real-time feedback:

• Control output ON/OFF indication: Shows the current state of the timer's output relay.
• Remaining time bar graph: A visual representation of the remaining time, indicated by a pattern of bars in tenths (1/10) of the set time.

Maintenance

The H3CA-A timer is designed for reliable operation with minimal maintenance. However, periodic checks can ensure optimal performance and longevity.

• Cleaning: Gently wipe the exterior of the timer with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Connection Check: Periodically inspect wiring connections to ensure they are secure and free from corrosion.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity limits to prevent damage.
