General Description 1.1 Overview The Montalvo Z4 Unwind dancer controller provides precise automatic control of web tension. The progressive PID regulator automatically compensates for roll diameter. The controller is used in a closed loop, of which the dancer and a brake (or other tension-affecting device) are part.
Ethernet/IP communication module includes HMI communication. Available on all models. COMPATIBILITY The Z4 Circuit Board is a drop-in replacement/upgrade for earlier Montalvo controllers: CB64, CB63 and DRT6 Replacement The Z4 design allows for easy customer swap, full compatibility and increased functionality.
Electrical Installation 3.6 Installation – Dancer Sensor The controller requires the use of a dancer arm position sensor. Montalvo offers two types: • DPS-1 - Solid state. Reacts to changes in angle/tilt. • MDP-6 - Potetiometer. Located at the dancer arm pivot point.
In a standard braking system, each brake pad is connected in parallel to the regulated air output. Stop Menu In a range expander system, pads are divided into groups called ranges using the Montalvo P4 (or Hold Menu P3000HD-RE) Automatic Range Expander. There can be between 2 and 4 ranges. Each range is Diameter Menu driven from a separate valve switch within the enclosure.
USB Drive HMI RS232 The Montalvo Z4 Controller, with Ethernet Option, can provide communication capability within an industrial Ethernet network (e.g. Ethernet/IP). The module for this option is factory installed. Existing controllers without the option can be upgraded by replacing the HMI Module (or cover plate) with the Ethernet Module.
