Spider System Hydraulics Control
Spider is meant here is not a family of eight-legged insects that are highly toxic and deadly if bitten by it.
Spider what I mean is a system control hydraulic which require a large force or torque for stirring small pieces of wood (chips) inside the digester or Impbin according to the desired speed to achieve the desired amount of production in the process to produce pulp in our factory. Control system used is called Spider Hydraulic Control System (Hagglunds). This control system direct control of two pumps which serve to drain the oil in the system in order to increase oil pressure above 250 bar antecedent control by a proportional valve. The larger the orifice of the proportional valve which is open the greater the amount of oil which passed into the system so that the oil pressure levels rise. With this high pressure control rotational speed of the digester and Impbin be in control. Controlling the maximum speed in our factory is 20 rpm. For treatment of a main board / card spider who does not much can be done. We do care only at every annual shut down. Flushing with clean air and re-check all terminal connections. To avoid loss of process pulp production we have to prepare a spare for main board.

Impbin

  

In the Company of our systems are installed in 6 locations: 3 in PM9 Impbin, HP-feeder and Outlet Devices Digester and 3 more in PM8 Impbin, HP-feeder and the Outlet Device Digester
For the PM9 has been run since 2007 and for PM8 still need to wait for tie ins to the Digester area.
The Spider problem that occurred in our company in Pulp Making-9 are:
1-Monitor in the control panel remains black while the system runs and can not be in control.
2-Alarm appears on monitor and the system stop, can not run anymore.

At first we felt confused handling although this system is simple but unprecedented. We try to replace the mainboard with a spare from Impbin PM8 (not yet run). We try to enter the parameters required (number of parameters about 22 pages type of A4 paper)
I will explain what we've done.
To save time and reduce the loss of production then we immediately replace it with a new card. We bring the damaged card to the office for the analysis of the problem. Connect spider control with a computer and receive data from the spider. To analyze and try to reset several times and re-enter the correct data, try to simulate with the simulator 4 ~ 20mA and connected output with proportional valve. To avoid and reduce the loss of production we have provided training to all members of the instrument.

How to grab data from Spider Control Panel (for Back up)
1-Connect power cable (220Vac,50Hz).
2-Connect output adapter 24Vdc to Spider control panel and turn on spider.
3-Connect cable usb to serial RS232 to Spider (serial RS232 side).
4-Connect Computer with cable usb to serial RS232 (usb side)
5-Open file "spidercom2.exe" in your computer.
6-Click tab "PARAMETER" than click "RECEIVE".
7-Wait a few moments. Computer will read and receive data from Spider Control Panel and when finished will display on monitor computer "DONE". When starting  receive data, the lights in cable USB / RS232 going on. Till to exit the word DONE in the computer than the lights off.
8-To view the data which has been in the store we could open with a click "DISPLAY" and then click "PARAMETERS". The file will appear and you can check all the existing data in the Spider Control Panel. Save your file before it by clicking "FILE" then "SAVE AS" as a unix file names in your computer's hard drive, for example,  "PM9Impbin". Files that are stored will have a ext. s2p or "PM9Impbin.s2p".
9-Completed.


How to send data from your computer to Spider Control Panel.
1-Connect cable USB to RS232 to a computer and Spider Control Panel.
2-Open the file has been updated to upload (save to Spider Control Panel) for example: PM9Impbin.s2p.
Once open, make sure the correct data and then we save it to Spider Control Panel Click "PARAMETERS" then click "Transmit".
3-When the transmit is completed it will come out the word "transmit okay" in your computer. The lights on the usb cable / RS232 going off.
4-To complete the process transmits the Spider Control Panel needs to be reset. Press the "RESET" once and wait for Spider Control boot ..
5-Spider Control Panel is ready to be operated by the process.
6-Completed.


I created this article so that we can share knowledge together. Much remains to be added because this is only a short writing course. If anyone wants to ask I'll try to answer.

Thank you.
