14.2.4 Installation MTC 2
The MTC2 can only be run in conjunction with a SIPLACE station and not as an independent machine.
The settings (machine data) are saved in the battery backed memory of the machine controller and are
only valid for this particular machine.
When the MTC2 has been delivered, the following steps must be performed before the machine is used
for the first time:
X Check the basic height and if necessary set it (see the User Manual).
X Check that the power supply has been set correctly (see Chapter 13.3.14 or Adjustment Instruction).
X Check that all axes can move freely.
X Check the toothed belt for correct tension and damage: See settings guide
X If there is evidence of damage to the toothed belt, it must be replaced (see the Service Instructions).
X Prepare the SIPLACE station (see Chapter 13.2.6).
X Dock the MTC2 onto the SIPLACE station (see the User Manual).
X Switch on the SIPLACE station and the MTC2.
X Log on to the station computer software at the Service access level.
X Start SITEST.
X In the basic view, switch to the menu for the MTC2 .
X Perform a reference run on the MTC2 .
X Perform a reference run on the SIPLACE station.
X Perform a functional test on the safety equipment by carrying out each of the following actions
individually during subsequent reference runs:
X Press the EMERGENCY STOP button.
X Open the protective doors.
X Leave the tower locking mechanism open before the reference run.
There must be an EMERGENCY STOP and a corresponding error message must be output on the
screen.
X Undo the relevant action and confirm the error message.

14.2.5 Modules of the controller
14.2.5.1 C167 controller board
The controller program (firmware) on the C167 controller board is saved in a flash EPROM. The version
number can be queried from the SITEST program.
The machine data and the set-up are saved in RAM. After the machine is switched off, the data is held
by a buffer battery (buffer time approx. 3.5 years), which is also located on the C167 controller board. In
addition, an electrolytic capacitor ("Goldcap") with a capacity of 1 F is fitted. This saves the data for
approximately 8 hours when the backup battery is changed.
The "neutral position" light barriers and the software limit switches are wired to the Masterdrives and are
made available there via the CAN bus of the controller.
Tasks:
Communicating with the station computer of the SIPLACE station
Controlling the machine via the firmware
Exchanging data with the axis controllers
Saving the firmware (flash EPROM)
Saving the machine data and the set-up (battery-buffered RAM)
Saving machine-specific parameters, such as serial numbers (in the EEPROM)
Providing a realtime clock
Inputs for sensors
Displaying operating statuses and error statuses via LEDs
Two RS232 interfaces (maximum transfer rate: 115.2 kBaud/s)
COM 1: Test interface for debugging service
COM 2: Free
