The UNIVERSAL TIMER UTR-2033 is a versatile industrial timer designed for various control applications, offering a range of operating modes and precise timing capabilities.
Function Description
The UTR-2033 functions as a universal timer capable of operating in several modes: Cyclic On Timer, Cyclic Off Timer, Delay On Timer, and Delay Off Timer. It supports both UP and DOWN counting directions. The device features a dual-display system: an upper 3-digit, 7-segment, 0.80" display for process time and a lower 3-digit, 7-segment, 0.40" display for set time. Input for triggering the timer can be from NPN/PNP Proximity sensors or a Micro Switch. Output is provided via a single relay with two changeover (C/O) contacts. The timer allows for flexible reset options, including a front panel reset and a terminal reset. Parameter settings are protected by a password to prevent unauthorized changes.

Usage Features
The UTR-2033 offers a user-friendly interface for setting parameters and monitoring operation.
- Key Operation:
SET key: Enters parameter setting mode, moves to the next parameter, saves and exits settings.SHIFT key: Selects the digit to modify when a value is edited.INC key: Changes the value of the selected digit.ENT/RST key: Saves and exits parameter settings, also functions as a reset.
- Operating Modes:
- Cyclic ON Timer: The relay turns ON for a set duration (ON Time 1), then OFF for another set duration (OFF Time 1), repeating for a specified number of cycles.
- Cyclic OFF Timer: The relay turns OFF for a set duration (OFF Time 1), then ON for another set duration (ON Time 1), repeating for a specified number of cycles.
- Delay ON Timer: The relay turns ON after a set delay time once the start pulse is received.
- Delay OFF Timer: The relay turns OFF after a set delay time once the start pulse is received.
- Parameter Setting:
- Access to parameter settings requires entering a password (default 25).
- Users can select the operating mode (Cyclic ON, Cyclic OFF, Delay OFF, Delay ON).
- For Cyclic modes, parameters include:
- Number of Repeat Cycles.
- Unit Selection for Cycle ON Time (Sec/Min/Hr).
- Range Selection for Cycle ON Time (9.99/99.9/999).
- Unit Selection for Cycle OFF Time (Sec/Min/Hr).
- Range Selection for Cycle OFF Time (9.99/99.9/999).
- For Delay modes, parameters include:
- Unit Selection for Delay Time (Sec/Min/Hr).
- Range Selection for Delay Time (9.99/99.9/999).

Maintenance Features
The manual provides clear guidelines for installation and maintenance to ensure the longevity and safe operation of the device.
- Mechanical Installation Guidelines:
- Requires a panel cutout of specified dimensions.
- Secured with clamps.
- Must be kept away from heating sources, caustic vapors, oils, steam, or other unwanted process by-products.
- Wiring should use specified crimp terminals (M3.5 screws) with a tightening torque of 1.2 N.m.
- Unused terminals should not be connected.
- Electrical Installation Guidelines:
- Power supply must be OFF during wiring to prevent electric shock.
- Use appropriately rated and twisted wires to reduce electromagnetic interference.
- Cable for power source must have a cross-section of at least 1mm and insulation capacity of at least 1.5kV.
- Standard power supply cable is recommended for better anti-noise effect.
- A circuit breaker or mains switch must be installed between the power source and supply terminal for easy ON/OFF function, accessible to the operator.
- Prevent metal pieces or clippings from entering the product to avoid safety hazards.
- Safety Precautions:
- All safety codifications and symbols in the manual must be strictly followed.
- Improper handling may impair the protection provided by the equipment.
- Read complete instructions before installation and operation.
- Warning: Risk of electric shock.
- General Maintenance:
- Regular cleaning of the equipment is necessary to prevent blockage of ventilating parts.
- Clean with a soft, clean cloth; avoid isopropyl alcohol or other cleaning agents.
- The fusible resistor must not be replaced by the operator.
- Environmental Considerations: Use and store the instrument within the specified ambient temperature and humidity ranges.
The UTR-2033 is designed for robust performance in industrial environments, offering precise timing control and ease of integration into existing systems.
