Foxboro P0924DB Terminal Base

Description

TAs are UL/UL-C listed as associated apparatus for supplying non-incendive field circuits Class I; Groups A-D; Division 2 hazardous locations when connected to specified 200 Series FBMs and field circuits meeting entity parameter constraints specified in Standard and Compact 200 Series Subsystem User’s Guide (B0400FA). They are also DEMKO certified as associated apparatus for supplying field circuits for Group IIC, Zone 2 potentially explosive atmospheres. Field circuits are also Class 2 limited energy (60 V DC, 30 V AC, 100 VA or less) if customer-supplied equipment meets Class 2 limits.

1、 Maintenance regulations, regular equipment testing, and adjustment regulations (1) Check the connection of the wiring terminals in the PLC cabinet every six months or quarter, and if any loose parts are found, promptly reconnect them firmly; (2) Re-measure the working voltage of the power supply to the host in the cabinet every month;

2、 The regulations for regular cleaning of equipment (1) The PLC should be cleaned every six months or quarter. Cut off the power supply to the PLC, remove the power rack, CPU motherboard, and input/output board in sequence, perform cleaning, and then install them in place. After all connections are restored, power should be transmitted and the PLC host should be started. Carefully clean the PLC box for hygiene; (2) Replace the filter screen under the power rack every three months;

3、 Preparation and maintenance procedures before maintenance (1) Prepare tools before maintenance; (2) To ensure that the functions of the components do not malfunction and the template is not damaged, protective devices must be used and anti-static preparations must be made carefully; (3) Contact the dispatch and operators before maintenance, and hang the maintenance tag where it is necessary to hang the maintenance tag;

4、 Equipment disassembly sequence and methods: (1) Shutdown maintenance requires two or more people to supervise the operation; (2) Turn the mode selection switch on the CPU front panel from “Run” to “Stop” position; (3) Turn off the main power supply to the PLC, and then turn off other power supplies to the module; (4) Record the wire number and connection position of the power cord connected to the power rack and remove it. Then, remove the screws connecting the power rack to the cabinet, and the power rack can be removed; (5) The CPU motherboard and I/O board can be removed by rotating the screws below the template; (6) Install in reverse order;

5、 Maintenance process and technical requirements: (1) When measuring voltage, a digital voltmeter or a 1% accuracy universal meter should be used for measurement. (2) The power rack and CPU motherboard can only be removed when the main power supply is cut off; (3) Before removing or inserting the RAM module from the CPU, it is necessary to disconnect the power supply of the PC to ensure that the data is not chaotic; (4) Before removing the RAM module, check if the module battery is working properly. If the battery fault light is on and the module PAM content is removed, it will be lost; (5) Before removing the input/output board, the main power supply should also be turned off. However, if production requires, the I/O board can also be removed while the programmable controller is running, but the QVZ (timeout) light on the CPU board is on; (6) When inserting templates, be extra careful, handle with care, and remove items that generate static electricity; (7) Do not operate with power when replacing components; (8) After maintenance, the template must be installed in place.
