Page 3: Ml Switch
Description The ML Switch (PR0109) is a device that allows up to 10 RDM ML controllers to be connected to an IP network, without the need for individual IP ML modules. There are 10 RS232 connections for linking to 10 ML controllers. There are 3 standard Ethernet Switch (10/100baseT) connections for other network devices. -

ML Switch User Guide Top View Connection to ML Controllers: Network Configuration Network Compatibility New ML Switch and IP Modules will be labeled identifying software version. New ML Controllers will not log on to network using pre 1.2 versions of ML Switch and IP Modules. Controllers with the following label will only log on to network using ML Switch or ML IP Module with software version 1.2 or higher. -

ML Switch User Guide RS232 Lead Lengths RS232 patch lead maximum length must not exceed 15 metres. (Ports 1 - 10) The 3-character address that will be seen on the system front end is determined by the position of the two Network ID rotary switches and the port the controller has been connected to, unless the connected controller has its own network ID rotary switches, in which case the controller ID will override the switch settings. -
Page 6: Pr0109-Phi User Guide
PR0109-PHI user guide The PR0109-PHI hardware version of the ML Switch allows for EEV control on an island by island basis. It also allows for the use of the energy feature trim control which pulses the trim relay of a ML case controller based on the actual shop floor humidity therefore minimising energy usage. - Page 7 ML Switch User Guide Click on “Configure” to set the type: - Then click “Type” Use the drop-down selection to select the type required and then click “Set Type” Parameters can be configured using the connection as illustrated above or through the ML Display, if fitted, or via the normal Data Manager change parameter routes.

Page 11: Eev Control Operation
ML Switch User Guide EEV Control Operation Ensure the transducer is correctly connected and the jumper is in the Pressure position. Once the Switch has been correctly setup, it will pass values to each of the controllers connected to ports 1 through 10. In an EEV application the evaporator in temperature probe reading for a case controller can be obtained from the ML Switch on which the controller is connected. -
Page 12: Humidity Control Operation
ML Switch User Guide Humidity Control Operation To utilise this feature a Humidity/Temperature Display is required (PR0445). Connect the Humidity/temperature display to the display port on the ML Switch. The control algorithm will use the humidity reading from the display in calculating the percentage at which the trim relays are to be pulsed. -
