Sterling SSC1-5Q service manual 6Configurable Settings, Options for Station Setup

6Configurable Settings

This section describes the proper setup of the SSC1-5Q control system parameters. These parameters are operator changeable; however, these items should require setup only during the initial installation. Only authorized personnel should change them.

Many of the variables and setup parameters have been preset at the factory and do not need to be changed. However, this section of the manual will address all of the setup parameters that were available at the time of printing. The purpose of this is to familiarize the reader with all the setup parameters and their usage.

6-1 Options for Station Setup

Name	Description	Default
Conveying Components
Convey time	Length of time the station’s vacuum valve remains open to	15 sec.
(CONVEY)	allow material to be drawn in. (For a volume-fill station, the
	valve closes when material covers the station’s volume-fill
	proximity sensor or this time elapses, whichever comes first.)
	Adjust this value to match the actual time needed to fill the
	station. To disable a station, set the convey time to Ø
	(zero).
Dump delay	Length of time allowed for material to drain from the station into	10 sec.
(DUMP)	the receiver. The controller will not attempt to deliver more
	material to the station until this time has elapsed.
	Adjust this value to match the actual time needed to drain the
	station. If it is set too short, the controller may attempt to refill
	the station before it is empty, causing material to back up
	and/or underusing the station’s capacity. If it is set too long, the
	system may be unable to keep up with your equipment’s
	demand for material. DO NOT SET TO “Ø”.
No convey	The controller issues a “no convey” alarm if it has repeatedly	3
(NO CONVEY)	attempted to convey material to the station but the flapper
	never opened during the dump delay. (The number of attempts
	is controlled by this setting.)
	The setting for this option depends on (a) how much material
	your injection mold uses to make each part compared with the
	capacity of the receiver and (b) how important it is to keep your
	injection mold from running out of material and shutting down.
	A higher setting will give you fewer alarms, at the risk of
	emptying the receiver without warning. A lower setting will give
	more frequent alarms, at the risk of disrupting operations
	unnecessarily. DO NOT SET TO “Ø”.
