The Honeywell TA3840 Data Processing Racks are integral components of the TA3840 or EMx40 system, designed for monitoring liquid cargo parameters on tankers. This system tracks essential measurements such as level, temperature, and pressure, along with other associated data from installed transmitters. The TA3840C communication unit, TA3840R remote display unit, and TA3840S safety unit form the core of this system. Additionally, the TA3840C A/D Analog data collection unit is part of the TA840 System.
The TA3840 system is primarily used for processing liquid cargo data on tankers. It consists of several racks:
The racks TA3840C, TA3840C A/D, and TA3840S are typically installed in a 19-inch cabinet. The TA3840R panel can be installed in a wall-mounting box or flush-mounted in a console.
The equipment is designed and manufactured in accordance with local safety regulations and European directives, including:
The TA3840S rack's manufacturer and specifications plate, located on the rear face, provides details such as:
The system is intended for professional use and requires installation, operation, and maintenance by competent and qualified staff. The maintenance menu, accessed via the UTILITIES menu (MODE and MNT) and a password ("6854" or system-defined code), offers several functions:
The RAW menu allows displaying raw values measured by each transmitter and modifying the measure reference from the bottom (zero line) or top (OFFSET) for radar transmitters. Various types of displays are available for different transmitters, including radar transmitters, analog transmitters associated with radar, and 4-20 mA analog transmitters. Users can enter values within suggested limits for offset and zero line modifications.
The HISTORIC menu saves the last 100 system fault events, including date, time, slave number, error code, and a description of the failure. Error codes range from 001 to 116, covering issues such as radar transmitter communication, invalid measurements (distance, temperature, analog), and monitoring communication faults.
Maintenance interventions should only be performed with electrical power off. Equipment must be wired by a qualified electrician, ensuring mains connection, grounding, circuit breaker, and protection conform to current standards.
Preliminary checks for system failures include:
A detailed troubleshooting table is provided for various observations, likely causes, and remedies for TA3840S Safety unit, TA3840C Communication unit, TA3840C A/D Communication unit, and TA3840R Remote display unit. Common issues include power supply problems, blown fuses, faulty boards (power supply, CPU, LCD display, radar transmitter supply, analog input, multifunction), ribbon cable connection issues, and communication faults. Remedies often involve replacing fuses, boards, or checking/securing connections.
Honeywell Marine provides sets of two EPROMs ("EVEN" and "ODD") for software updates. These EPROMs must be inserted into the relevant electronic boards, taking care not to damage the pins. Specific software versions are:
Detailed instructions are provided for removing and installing various electronic boards and replacing fuses:
Two standard fuse kits are supplied:
A claim report (Annex A) must be filled out and faxed to Honeywell Marine for any service requests or spare part needs. This report is required before any intervention. A return for repair form (Annex B) must accompany defective equipment sent back to Honeywell Marine, providing details to identify the defect and facilitate repair. The form includes sections for instrument description, problem description, application details, and a declaration of equipment cleanliness and decontamination. Equipment should not be sent before receiving an RMA number.
