The Mercury 3 Range

From Resource Data Management

For Version 1.0M & 1.0E

The Mercury Mk3 controller is primarily intended for use in refrigeration display cabinets or coldroom applications. It will switch the

evaporator valve (LLV or EEV) based on the value of its temperature or pressure input. It has outputs to control lights, fans, suction valve,

trim heaters and defrost control. It can have variable inputs for reading a pressure transducer along with two digital inputs that can be

added to, by utilising the switched resistors feature.

The controller has many features, some of which are energy saving, such as pulsed trim heaters or the case off with lights parameter

(see parameter section for further details). There are several hardware variants of the Mercury Mk3 controller split into two types; an E-

version that has Relay 1 as a Solid State Relay for switching EEVs and the second is an M-version that has Relay 1 as an electro-

mechanical relay for switching solenoid LLVs. For these two types, there are further options of adding analogue inputs, choice of serial

or built in IP communications along with either a remote or integral display option (see ordering information for more details).

The controller supports PT1000, NTC2K, 470R, 700R, 3K, 5K, 6K, NTC2K25, NTC10K or NTC10K(2) temperature probes.

Note: probe types cannot be mixed.

Hardware Variants

As mentioned above, the Mercury 3 controller offers a number of choices concerning the physical hardware including choice of IO,

Display and communications type. Furthermore depending on the valve type (electronic expansion or mechanical solenoid valve) the

option of either a solid state or mechanical relay is available. For specific part numbers see Ordering Information.

Note: The controllers are delivered pre-configured as Type 1 and Type 3 for variants M and E respectively.

Compatible Network Interfaces

Mercury controllers which do not have an IP interface built in are capable of connecting to either a TCP/IP local area network, an RS485

Genus compatible network, an RDM wireless mesh network or they can be used in standalone mode with no network output. To connect

to a network you must add the correct communications module. Connecting to any of these communication modules will automatically be

detected on power up and will affect the ‘Net’ menu set up screens available to you. Note controllers with built in IP will be able to

communicate to any IP switch, including the rear ports of the RDM Mercury Hub.
