Control panel portable

Control panel portable

Portable control panels (VPU-1, VPU-2 or VPU-3) are intended for manual control by traffic light object at distances to 150 m and can be installed on posts of traffic police including for control of the traffic light on an entrance to a post.
The VPU-1 panel allows to cause four phases (including TVP), and also a phase of the yellow blinking (YB), and a phase of the disconnected state (DS). The VPU-2 panel allows to cause eight phases (including TVP), phases ZhM and OS; and also to 8 programs of management (so-called "green streets"). Pudt VPU-3 by opportunities is identical to VPU-2, but has more difficult control interface. Really the ASS-UD protocol (L1, L2) allows only 4 inquiries of "green streets" (support is realized in road KDU-3N, KDU-3S controllers). LED indication of number of a phase or promtakt is provided in all panels.
For the road controller the team with VPU is one of the most priority (On a priority above only the ZhM and OS toggle-switch on the assembly panel). If the panel is switched off, the road controller works or is autonomous, or under control of the ASUDD center.
VPU-1, VPU-2 panels are intended for work with KDU-3M, KDU-3, KDU-1 controllers dorab. Contact with the controller is carried out on the RS-485 interface (twisted couple in the screen). VPU-3 allows collaboration with KDU-3N, KDU-3S.
The device is placed in the splash-proof metal case, is powered from the controller or other source which is galvanic untied from a network 220B + 12B. The cover of the panel opens a key of the road KDU-3 controller. The key is necessary for VPU-3.
