Mercury Coldroom Panel Installation Guide The Mercury Range From Resource Data Management The Mercury Coldroom panel has been specifically developed to suit a variety of coldroom needs. The purpose developed enclosure has a detachable display/keypad for applications where the main enclosure is required to be “out of reach”. The panel is available with or without a main isolator switch. Each internal circuit has either fuse or circuit breaker protection.

Mercury Coldroom Panel Installation Guide Probe and Alarm inputs Note: When wiring in the probes to the connector, ensure that the 3 wires fitted to the probe connector (not shown on the diagram below) are not moved and remain firmly connected. These wires are used for the external digital inputs; door-open and entrapment. The resistors for the digital inputs are already present on the PCB and therefore external resistors are not required to signal door-open and entrapment alarms.

Mercury Coldroom Panel Installation Guide Setting up the Panel Access to the Panel can be achieved by the following methods: Through the front panel keypad Direct access by PC or palm top into the RS232 comms port. This requires a software package (Communicator) available on the RDM website Direct access by PC using Ethernet (IP-L) and an IP browser (e.g. Internet Explorer) Through legacy front end panels on 485 networks Through the RDM Data Manager.
Mercury Coldroom Panel Installation Guide Recommended set-up method If you are not connecting to a network and want to set up the controller through the buttons we recommend you use the following order from the function menu. rtc. Real time clock (This will automatically synchronise on network systems) a. b. c. d. e. f. g. h. i. j. Use the up or down buttons to scroll through the display until the display reads “rtc” Press enter. The display will show “t-1”.
Mercury Coldroom Panel Installation Guide PArA. Set/view parameters (This can be achieved at the network front end) a. From the function menu scroll to select PArA b. Pressing Enter while PArA is displayed will enter the parameter menu. The first parameter option will be displayed as P01. Pressing the Up or Down button will present the other parameter options P-02, P-03 etc. See the parameter list below to find what parameter number corresponds to which actual parameter.

Mercury Coldroom Panel Installation Guide Switched Resistor Values For PT1000 probes use 820 Ohm switched resistors. For NTC2K and NTC2K25 probes use a 590 Ohm switched resistor. For NTC10K probes use 2k7 Ohm switched resistors. For NTC10K(2) probes use 2k2 Ohm switched resistors. The resistors used must have a tolerance of 1% or better and the resistor must have a power rating of 0.25W. For improved accuracy whilst using switched resistors RDM recommend resistors with 0.1% accuracy are used.
Mercury Coldroom Panel Installation Guide Modifying controller states During normal operation you can change the following states from the function menu Fans Only “FAnS” Selecting the Fans Only option will put the controller into the Fans Only state if the current state is not Fans Only. If the current state is Fans Only then the controller will change to the Normal state. Selecting this option will exit the setup menu automatically.

Mercury Coldroom Panel Installation Guide Display Remote Mounting The display section of the Coldroom Panel can be removed for remote fixing. Unscrew the two front panel screws; take of the display front and then remove the 4 screws housing the display back onto the main enclosure. The display has a 5 meter cable which requires to be uncoiled from its internal location. Ensure that all power is disconnected before this operation.

Mercury Coldroom Panel Installation Guide Appendix 1 For later hardware revisions of Coldroom panels the Compressor/LLV and Defrost MCB/Fuse can be interchanged to allow the higher rated MCB/Fuse, 20A, to be used on the Compressor/LLV relay output and the lower rated MCB/Fuse, 10A, to be used on the Defrost relay output. By default the Coldroom panel ships with the 20A MCB/Fuse fitted to the Defrost relay and the 10A MCB/Fuse fitted to the Compressor/LLV.
Mercury Coldroom Panel Installation Guide 7) Remove the fixing plate. Swap the MCB in position “F5 Defrost” to “F1 Compressor/LLSV” and the MCB from “F1 Compressor/LLSV” to “F5 Defrost” taking note of the orientation of the MCB. The image below shows the view of the Coldroom with the fixing plate removed. 8) Ensure the MCB’s are securely fitted and the desired rated MCB’s are in the appropriate positions before re-inserting the fixing plate.
