MDC-360C DEPOSITION CONTROLLER
CONTROLLER INSTALLATION 8-4
I/O card, PN# 179239, has 12 to 120 volt AC/DC inputs. The Active inputs are
set true, assuming the input’s true level is set to High, by supplying 12 to 120 volt
AC or DC across the input pins.
Both cards have the same relay output scheme and use the same D37P connector.
The only difference is the Active I/O card’s connector is keyed such that it cannot
be inserted into the Passive I/O card’s connector.
There are two I/O card slots in the MDC-360C and they function identically.
Either card type can be inserted into either I/O slot. The vacuum system side of
the I/O cards requires a socket connector with receptacle crimp pins equivalent to
AMP 205562-2. Figure 8-7 shows the pin configuration and Table 8-4 supplies
pin signal assignments for both types of cards. Refer to Section 4.3.3.2 and
4.3.3.3 for I/O programming instructions.
8.3.8 DIGITAL-TO-ANALOG CONVERTER (DAC)
The Digital-to-Analog Converters are interfaced via a 7-pin, circular mini DIN
connector. The vacuum system side of the interface requires a connector
equivalent to the CINCH MDX-7PI. Figure 8-4 shows the connector and Table
8-1 shows the signal assignments.
8.4 POWER SWITCH
WARNING: Do NOT use the power switch as a disconnecting device;
disconnect the power cord from the power entry module to fully remove
hazardous voltage from inside the controller.
The power switch is located on the front lower left of the MDC-360C. Toggle the
switch to
I to turn the controller on, or to O to turn it off. The MDC-360C is off
when the LCD and all of the LEDs are off. However, turning the power switch
off does not fully remove the AC power from inside the unit. Always disconnect
the power cord from the power entry module to fully remove AC power from
inside the unit.
8.5 CONTROLLER COVER REMOVAL
WARNING: Under no circumstances should the MDC-360C cover be removed
without first removing the line voltage cord, as dangerous voltages are present
inside the case.
WARNING: The controller contains no user serviceable parts. Only trained
technician should attempt to service it.
CAUTION: To prevent damage to internal components by means of
electrostatic discharge (ESD), wear a grounded anti-static wrist strap.
