The Gefran 40A 48/40A 96 is an alternating current/voltage indicator and interceptor, designed for panel mounting. It provides clear visual feedback through LED displays and offers extensive configuration options to suit various industrial applications.
This device serves as a precise indicator for AC voltage and current, with the ability to intercept and manage alarms based on configurable setpoints. It can display process variables, alarm states, and configuration messages. The indicator supports various input types, including AC voltage (2V, 20V, 200V, 500V) and AC current (20mA, 50mA, 200mA, 1A, 5A), making it versatile for different measurement needs. It features up to three configurable alarms, which can be set as absolute, deviation, or symmetrical deviation types, with adjustable hysteresis. The device also includes logic inputs for functions like alarm memory reset, hold, flash, zero, and peak value selection, as well as relay, logic, and triac outputs for control. An optional analog retransmission output (4-20mA) is available for integration into other control systems.
The device offers a user-friendly interface with a clear LED display and three mechanical keys for programming and configuration. Parameters can be adjusted for various functions, including decimal point position, input scale limits, offset correction, hysteresis for setpoints, digital input functions (e.g., hold, flash, peak display, alarm reset), and output settings (alarm type, filter modes). The "F" key provides access to different configuration stages and confirms parameter changes. The "Raise" and "Lower" keys facilitate numerical parameter adjustments, with speed proportional to the key press duration.
Special functions like "HOLD" and "FLASH" enhance operational flexibility. In "HOLD" mode, the input value and alarms are frozen when the logic input is active, and a reset turns off relay outputs and alarm latches. In "FLASH" mode, the input value is sampled, alarm states are not transferred to outputs, and outputs are "frozen," but updated according to calculated alarm states when the logic input is active.
The device supports current transformers for measuring higher currents, with various models available for different primary current ratings (25A to 50A) and secondary outputs (2Vac or 4Vac). An optional RS323 interface cable and programming software are available for PC-based configuration.
Maintenance and repairs should only be performed by trained and specialized personnel. It is crucial to cut power to the device before accessing internal parts. The case should not be cleaned with hydrocarbon-based solvents (e.g., Petrol, Trichlorethylene) as these can reduce mechanical reliability. Instead, a cloth dampened in ethyl alcohol or water should be used to clean the external plastic case. The manual emphasizes that the warranty excludes defects caused by any use not conforming to the provided instructions.
The manual includes critical warnings for installation, connection, and use. It highlights the importance of using suitable cables, ensuring proper grounding, and separating power supply lines from input/output lines. The device does not have an ON/OFF switch and powers on immediately when connected. For safety, a two-phase disconnecting switch with proper marking, easily reachable by the user, is required for permanently connected devices. The device should not be used in inflammable or explosive environments unless suitable interfaces are employed. It contains components sensitive to static electrical discharges, requiring appropriate precautions during handling. The equipment is intended for permanent indoor installations within an enclosure or panel. It is crucial to avoid dust, humidity, corrosive gases, and heat sources, and to ensure proper ventilation. The manual also provides detailed guidelines for input and output connections, including the use of twisted and screened cables for analog inputs and RC groups for inductive loads.
