Job Cycle Timing Diagram
Timing recommendations:
• Use discrete signals when possible, especially for the Go signal. Use optional I/O Cable 128441 for discrete
signals.
• Use a 50 ms delay between bits.
Automation Control Ready in the following diagram represents:
• Pump is active
• No active alarms
• ADM is in Remote mode

A job cycle can only be completed on the active pump
ᶭ
+ Can
only
be used through the fieldbus; and
must
be used to operate the system. Styles 17-99 can only be operated through the fieldbus.
Ƒ Pre-charge will only be active when there is a set-point stored in the display or passed over the CGM.
¸
‡ The dispense complete is optional. This bit summates the volume dispensed any time it is triggered. Dropping the style strobe will also summate the volume dispensed.
^ Disabling the pumps(s) is optional. Does not diable heat.
The signal source can be either discrete or fieldbus. Go to "Style Definitions", then navigate to "Style Integration Setup" screen define the source. However, it is highly
recommended to use the discrete signal for proper timing.

CGM I/O Sequence
Function Sequence Description
Pre-Job Cycle
1
Check that Heartbeat is toggling ON and OFF at 1Hz.
2
Check that System Active bit is ON.
If System Active bit is OFF, Turn ON System Enable bit.
3
Check that Automation Control Ready bit is ON. Note: Active only when there are no active
alarms, the system is enabled and the system is in REMOTE mode.
If Automation Control Ready bit is ON, Turn ON PLC Lockout bit.
4
Check that PLC Lockout bit is ON.
If PLC Lockout/Control bit is ON , Enter desired Style Number (16bit integer).
