Device test

Accessible only to the Key Operator and technician

Device Test allows the Key Operator or technician to exercise independently several of the folder’s key functions.

The crossfold stepper motors may be run at the same time as their related solenoids are energized. For example, select STP–Shift (L) to run the shift stepper motor in the left-hand shift direction, then press +> as needed to display Shift Wheels. Now press the indicated button to energize the shift solenoids with the stepper motor still running. Press +> again to return to STP- Shift (L). In a similar way, the pullback stepper motors can also be run at the same time as the pullback solenoid is energized.

NOTE: Only two solenoids can be energized at any one time. Solenoids automatically time-out after 15 seconds to prevent over-heating – which can also be caused by repeatedly re-energizing them without a pause to allow cooling.

Fold Selection and Editing (Assign folds, Assign handfeeds)

Accessible to the Key Operator and technician

These functions allow the Key Operator to add/delete fold programs, and to modify bookfold binding margins, etc.

Although there are approximately 70 different fold programs stored in the folder firmware, a given user will be interested in only a few of them. The most popular programs have been collected into groups, called Fold Banks, each containing up to 10 programs, see Section 9. The programs included in each Fold Bank are targeted to the local conventions of a specific geographic market.

Select the appropriate Fold Bank number from the Parameters list under the System Menu. This action loads the set of programs contained in the Fold Bank to NVRAM, which in turn provides a program list to the operator’s control panel, and also makes the same list available to the Host Controller. NOTE: This action loads the handfeed menu as well as the on-line folding menu. Fold banks can only be changed by the technician.

Once the Fold Bank has been selected, the NVRAM program list available at the operator’s control panel and the host controller may be edited. This allows programs to be added, or deleted by the Key Operator to simplify the selections available to the user. But note that the Fold Bank itself is in firmware and cannot be changed. Editing is confined to the list in NVRAM.
