The Mercury Switch
From Resource Data Management
Description
The Mercury Switch (PR0018) is a device that allows up to 10 RDM Mercury controllers to be connected to an IP network, without the
need for individual IP Futura modules. There are 10 RS232 connections for linking to 10 Mercury controllers. There are 3 standard
Ethernet Switch (10/100baseT) connections for other network devices. The Ethernet ports are self configuring for uplinks and standard
10/100 Base T device connections.
As well as the Switch function there is the option for Island EEV control. This control can be achieved by using a transducer connected to
the Mercury Switch 4-20mA input or from a remote Suction pressure reading sent across an IP network from a Mercury Plant Pack
controller. Island trim heater control can also be achieved through the display port using a humidity temperature display (PR0445). To
utilise either of these features then the PR0018-PHI build option would be required.
Software version 2.2 and higher has the capability for CO2 Load shedding.
See RDM Data Manager User Guides for more information on CO2 Load Shedding

Note:- The display port, mA input and mA input selector are fitted on the PR0018-PHI only.The mA input is available for Pressure

this product
Connection to Mercury Controllers:
Using a standard CAT5 patch lead, connect the serial output of the RDM Controller to one of the RS232 ports of the Mercury Switch.
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.
Connection to other IP equipment
Use a standard CAT5 patch lead to connect other IP equipment to the Mercury Switch (such as a Futura IP module) into the 10/100 Base
T ports 1, 2 or 3.
Connection to another Mercury Hub/Switch or Other Ethernet Hub/switch
Use a standard CAT5 patch lead from any of the 3 10/100 Base T ports into any of the 3 10/100 Base T ports on the upstream Mercury
Switch. The 3 10/100 Base T ports are all self configuring.
Connection to a Data Manager/Director
Use a standard CAT5 patch lead and connect the Data Manager or Data Director to one of the 3 10 Base T ports.
10/100 Base T connectors
The three 10/100 Base T connectors have 2 LED’s adjacent to them: The green LED; when static, indicates that the connection to the
device is good, the green LED then flickers when data is being transmitted.
When the amber LED is permanently on it indicates that the connection is full duplex and if there is an error or fault on that channel the
LED flickers.
Network ID
The 3-character network ID is made up from the positions of the 2 rotary switches and the RS232 connector number. We recommend
that the 2 rotary switches are set to the Bay number and that the case sections are plugged into their corresponding RS232 port
numbers.
E.g. Bay 10 case 2:
The 2 rotary switches set to "1" and "0", controller plugged into port 2. The ID then is seen as "102" at the system front end.
Note that case number 10 would plug into RS232 port 0 (right most port) and come through as "100".
ID for equipment with rotary switches.
For RDM products that use the 3 rotary switches for the network ID (such as Mercury Power tray), the ID will follow what is set on the
controller local switches and NOT the port position on the Switch.

PR0018-PHI User Guide
The PR0018-PHI hardware version of the Mercury 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 Mercury case controller based on the actual shop floor humidity therefore
minimising energy usage.
Access to configure the Mercury Switch can be achieved by 2 ways.

ID
Allows the user to assign a unique three digit software address to the Mercury Switch. Note this is only required when the Mercury Switch
is in IP-L mode.
a. From the function menu scroll to select Id
b. The current id number will be shown. Use the up/down buttons to scroll through from 000 to 999.
c. Select the desired number and press enter to save.
Network Configuration
Unlike the PR0018 (Standard Mercury Switch version) when this product is used with a Data Manager/Data Director it is registered on
the system as a device. Once the Mercury Switch is on-line, the Switch type and parameters can be set up. The switch comes online with
the ID of the 2 rotary switch settings followed by the letter a. For example with the first rotary switch set to 4 and the second switch set to
8 then the switch would appear as device “48a”. If a DHCP server is present on the IP network set the 2 rotary network switches to an
appropriate setting, the Mercury Switch has an auto-initialise function, which will automatically log the device onto the site network. If the
wrong ID has been entered onto the network, you will have to reset the Switch ID by setting the ID to 0-0, power cycle and then re-enter
the correct ID.
This Switch does not require an external communications module.

Remote 2 –Uses the Remote Plant controllers Transducer Input 2
Remote 3 –Uses the Remote Plant controllers Transducer Input 3
Note: Mercury Switch pressure units must match that of the Plant Pack controller it is mapped
to e.g. both devices have to be set to Bar or PSI

EEV Control Operation
Product PR0018-PHI is intended for EEV control on an Island by island basis and can be implemented in two ways.
1. Using the on board 4-20mA Input to measure the suction pressure going to the island.
2. Using a remote suction pressure sent from Mercury Plant Controller (PR0600-PACK) on the same IP network. Note this remote
pressure can be shared by more than one Mercury Switch.
On board 4-20mA Suction Pressure Input Control Application
Ensure parameter P-57 is set to “Local”.
Configure the remaining parameters.
Connect the suction pressure transducer for the Island to the 4-20mA input on the Mercury Switch.
Ensure the transducer is correctly connected and the mA input selector jumper is in the Pressure position.
Ensure each Mercury case controller has been configured to accept the calculated remote evaporator temperature. See
Mercury user guide for further details.
Remote Suction Pressure Application
Ensure parameter P-57, Evaporator Type, is set to Remote 1 or Remote 2 or Remote 3.
Set parameter P-56, Broadcast ID, to match the ID of the desired Plant Pack Controller.
Configure the remaining parameters.
Configure the desired Plant Pack controller to broadcast the Suction pressure. See RDM Plant Controller PR0600 for further
information on how to broadcast pressure.
Note
If the Plant/Intuitive Pack Controller being read from is set to Bar then the Mercury Switch has to be set for Bar (Type 1 or 3)
If the Controller being read from is set to PSI then the Mercury Switch has to be set for PSI (Type 2 or 4).
To disable local transducer
To disable the local pressure input if it is not being used and stop it alarming transducer fault.
Set P-02 (Span) = 0. This only applies to software version 2.1 or higher.
