For this reason, it is necessary to remove the unit door and perform modification work in another place. In such a case, if the control unit whose door is to be removed is in the middle of the arrangement of the control center, it is impossible to remove the door while the control unit above it is in operation. Therefore, the door is removed after waiting for the control unit to stop, and the upper control unit is in the operation stop state during that period, so that the load cannot be continuously operated. (2) As described above, the control center is used as an accessory to the production of products. Therefore, the total height is limited (usually 2300 mm). Increase in load, etc.
The height of the control unit (200 mm as a standard, 300 mm, 400 mm, and 600 mm in addition to this) may change due to changes in the capacity of the control unit, etc., and the number of control units initially installed may change. For example, the control units provided in 9 stages (200 mm × 9 stages) may be changed to 8 stages (200 mm × 6 stages, 300 mm × 2 stages). In such a case, in the conventional control center, not only the position of the partition board needs to be changed, but also the attachment position of the hinge needs to be changed and adjusted, which causes a problem that the modification is troublesome.
