SECTION 5.17
Layer number ID# 900-999
The current layer # is indicated by this ID#. ID 900 is true when the process is stopped ("#" sign
shown on display).These IDs can be only used as inputs to an I/O equation using the I, P, and N functions.
Example: The I/O rung 1: N904 T14 causes output relay 7 to close for 1 second after the end
of layer 4 in a process.
SECTION 5.18 Hand Controller Push Buttons / Front Panel LEDs and
Function Keys
The Hand Controller, see Figure 5.13, was designed to increase, decrease, or terminate the control
voltage to the deposition power source while in manual operation. When the Model 880 is not in the
manual mode the three keys can be used for other functions. The keys INC, DEC, and STOP have been
assigned ID's which allow them to be incorporated into an I/O program.
