Description
The RDM Brooklands control tray PR0029L-ACF is a control system. The tray is used in conjunction with
the Brooklands wiring loom which connects to the tray using a 19 pole multiway connector. This loom
connects to all the low voltage components in the cabinet, these being the temperature probes,
refrigeration solenoid valve (24vdc), evaporator fans (24vdc) and a fan fail signal (volt free). There is a
separate mains voltage connector which connects to the cabinet lights. Two versions of the Brooklands
tray (PR0029-ACF & PR0037) have an additional mains connector for use with mains voltage evaporator
fans.
The tray is designed to be used on sites utilising a standard refrigerant or CO2.The unit has a Solid State
Relay (SSR) and through the in-built software the user can set the valve type for Mechanical Liquid Line
Valve (LLV) or Electronic Expansion Valve (EEV) control. The PR0029L provides a varying low voltage
output supply to control the evaporator fans. The PR0029L ACF and PR0037 provides a mains feed to
control the evaporator fans, the PR0037 has the addition of a higher specification relay to drive LED lights.
The RJ45 connector found at the rear of the tray is a serial RS232 port and must be connected to an
appropriate communications module such as an IP Futura Module (PR0016) or Mercury switch (PR0018 or
PR0018-PHI) or RS485 Legacy Module (PR0026). This allows communication with compatible front ends
such as the RDM Data Manager or Data Director.
The RDM Brooklands tray PR0033 is fitted with an electro-mechanical relay to drive a LLV and the PR0033E
has an SSR to operate an EEV. The PR0033/E series control tray is designed to be used only on IP networks
only and must be connected to an appropriate IP communications module or Mercury Switch. The tray has
the addition of a PWM (Pulse width modulated) output for controlling intelligent evaporator fans. The
controller has a “CO2 App parameter” to allow them to be used in conjunction with an RDM Data Manager,
Plant Pack Controller and CO2 Pump Station for load shedding on CO2 sites.
Addressing
The controller will log onto the network when it is first powered up. You must set the address using the front
accessed rotary switches prior to power up. If you change the location of a tray from one case section to
another, you should change the rotary switches to the new address before powering up the tray in the new
location.
NOTE: V1.3 software does not support Genus RS485
networking.
Id
To set the network id, use the front accessed rotary switches and set the address of your choice. Each device
on the network must have a unique address number.
(Normally set to Bay/case number such as 103 = Bay10 case 3)
Parameter Settings
All parameter settings are modified using the RDM Data Manager front-end alarm panel, a service or install
level password is required to alter any settings. Default settings are shown below
Valve Type Selection
The PR0029L & PR0037 Brooklands control tray has a parameter to set the valve type (EEV or TEV) via the
front end if the controller software is version V2.0 or higher or V7.5 or higher. On earlier software versions,
V6.9 or above, the valve type can only be changed using a PC connected to the controller. If the tray has V1.4
software then the valve type cannot be changed and is fixed as EEV only. The default factory setting is EEV.
The PR0033 Brooklands control tray can only be used with a thermostatic expansion valve (TEV).
The PR0033E Brooklands control tray can only be used with an electronic expansion valve (EEV).
On the PR0033/E range there is no user settable parameter to set valve type, this is fixed to the hardware type
PR0033 or PR0033E.
See RDM Data Manager user guides for more information on CO2 Load Shedding

Case Lights
Timers either locally in the tray or remotely at the front end normally control the case lights automatically. If
there are no timers set up from the front end or if there is no network connection, the lights default to on.
On Line Status
The case status indicator is used to display the network status: -
Alternate Red/Green: - logging on
Alternate Red/Green/Amber: - has address but not on-line
Fixed temperature band colour (Red, Green or Yelllow): - online
Connections
There is No status indicator on this version of the Brooklands Tray. The RS232 serial port of the
communications module plugs into the rear of the tray (RJ45 connector). All case wiring connects to the two
flying leads at the back of the tray. (19 way and 3 way)
The power lead plugs into the rear of the case and is the ONLY method of isolation. The power lead must be
removed before the lid is removed.
Case Clean Switch
THIS IS NOT AN ISOLATOR. The case clean switch will turn power off to all outgoing circuits and send
signals to the front-end indicating the case has been manually switched to case clean mode. The controller will
remain powered and will continue to communicate with the front end panel which will only generate an offline
alarm if there is a genuine power failure or communications failure.

Parameter Descriptions
Parameter
Description
Yellow Cycle temp.
When the temperature band is set to yellow range (see Temp. Band Parameter Below) this
will be the cut in temperature.
Red Cycle temp.
When the temperature band is set to red range (see Temp. Band Parameter Below) this will
be the cut in temperature.
Green Cycle temp.
When the temperature band is set to green range (see Temp. Band Parameter Below) this
will be the cut in temperature.
Cut-in diff.
This is the differential below cut in temperature where refrigeration will cut out.
Control weight
Percentage of the Air-On temperature that is used to calculate the control temp. The
remaining percentage will be used on the Air-Off temperature. Example;
P-03 set to 30% Control temp = 30% Air-on and 70% Air-off
Superheat Ref.
The controller will attempt to maintain this superheat value (EEV only)
EEV Prop. Gain
These are the parameters to fine tune the valve PID feedback control loop, these
parameters should be left as default and only be changed in exceptional circumstances.
EEV Integ. Gain
EEV Integ. Time
Fan Speed
The fan speed output will run the fans depending on the voltage set at fan speed parameter
(1 = 16Vdc. 2 = 18Vdc. 3 = 20Vdc. 4 = 22Vdc. 5 = 24Vdc. (PR0029 only))
The PWM output (PR0033 & PR0033E only) will run the evaporator fans at this pre-set
percentage of full speed (PWM Parameter).
PR0029L ACF and PR0037 trays have fixed speed mains fans.
Temp. Band
This selects the temperature band that the cabinet will run at, yellow, red, green or
ambient, this is set according to the type of product in the cabinet. Temperature alarm
settings will automatically change accordingly.
Probe Type
As standard the tray uses PT1000 temperature probes however NTC 3K probes can be used
by setting this parameter to 1.
Note that the log probe remains as a PT1000
Evap Select
The superheat for EEV control can be calculated using different means to suit the
application.
Local - Based on the value of the Evaporator and Suction line temperature probe inputs
connected directly to the controller.
Rem1 - The local suction line temperature probe and a local suction pressure measured by
a transducer connected to the refrigeration case island Mercury Hub (PR0018-PHI). The
pressure read from the Mercury Hub pressure transducer is converted to a temperature
based on the gas type being used by the system. This temperature is transmitted to all
controllers connected to the Mercury Hub.
Rem2/3 - Not used at present.
Div Value
This parameter is used in conjunction with a Mercury Switch pressure application (Evap.
select set to Rem1). When the Mercury Switch generates the MOP (Maximum operating
pressure) alarm the controller reduces the maximum valve opening to this percentage. For
example if this parameter is set to 50% and the MOP alarm is generated then the
maximum valve opening will be limited to 50%. Therefore as the controller pulses the valve
the maximum the valve will open is 50%.
Ctrl Probe Type
Switches between using the air-on probe(s) and the Logging probe. Note the control
temperature will still be a derivative of the weighted average of the control probe + Air-off
probe(s)
PWM
Pulse Width Modulation, this applies only to trays with PWM controlled fans (PR0033 &
PR0033E), this is the percentage of maximum speed the fans will run at.
Valve Type
Selects between mechanical liquid line valve (LLV) and electronic expansion valve (EEV)
Co2 App
When used in conjunction with a Data Manager load shedding system, this parameter
selects how the valve and fans will operate if a load shedding signal is received from the
Data Manager.
Mode 1 –Evaporator fans off, valve open 100% on Load Cycling
Mode 2 –Evaporator fans off, valve closed to 0% on Load Cycling
Alarm delay
Delay for the over and under-temperature alarms
Yellow UT Alarm
Under temperature alarm set point when set to yellow range. This alarm uses the control
temperature.
Yellow OT Alarm
Over temperature alarm set point when set to yellow range. This alarm uses the air off
temperature.
Red UT Alarm
Under temperature alarm set point when set to red range. This alarm uses the control
temperature.
Red OT Alarm
Over temperature alarm set point when set to red range. This alarm uses the air off
temperature.
Green UT Alarm
Under temperature alarm set point when set to green range. This alarm uses the control
temperature.

Defrost Start
When defrost mode is set to “Local”, this is the start time for the 1st defrost
Defrost Number
When defrost mode is set to “Local”, this is the number of defrosts per day equally spaced
from the start time.
No Defrost Time
If the controller misses a defrost command for any reason, a defrost will initiate after this
time has elapsed from the last defrost. Normally set to 2 hours over the normal defrost
period.
Def. term. temp.
The defrost will terminate when the temperature of the air off probe(s) reaches this value.
Defrost min time
Minimum time that a defrost will use. Defrost can’t terminate until this time has elapsed. If
termination temperature is reached during this period the controller will not continue the
refrigeration cycle until the end of the defrost min period.
Defrost max time
Time period after defrost minimum that defrosts are allowed to terminate.
Drain down time
A period after defrost period to allow the draining of any surplus water.
Recovery time
The valve is switched on at the start of this period to allow the temperature to recover to
the normal operating point. This period also inhibits the OT alarm.
Note that if the air-off temperature is still above the OT alarm setpoint when this period
expires, an immediate OT alarm occurs; there is not a further alarm delay.

18Vdc. 3 = 20Vdc.4 = 22Vdc. 5 = 24Vdc. (PR0029 only))
The PWM output (PR0033 & PR0033E only) will run the evaporator fans at this pre-set percentage of full speed
(PWM Parameter).
Before Adjusting the fan speed parameters firstly determine the fan type fitted to the case.
PR0029L ACF and PR0037 trays have fixed speed mains fans.
CO2 App
Needs to be set to Mode 1 or Mode 2 when using CO2 Load Cycling
Mode 1 –Evaporator fans off, valve open 100% on Load Cycling.
Mode 2 - Evaporator fans off, valve closed 0% on Load Cycling.
Probe Type *
NTC 3K Probes can be used by setting this parameter to 1.
Note that the log probe remains as a PT1000
When used in conjunction with a Mercury switch (PR0018-PHI)
EEV Control using Pressure
The Mercury Switch (PR0018-PHI) can be used for EEV control on an island by island basis. In an EEV
application the evaporator in temperature probe reading for a case controller can be obtained from the Mercury
switch on which the controller is connected. A suction pressure transducer is connected from the case Island to
the 4-20mA input of the Mercury Switch and the pressure read from this transducer is converted to a
temperature based on the gas type being used by the system. This temperature is transmitted to each
controller (Rem Evap Temp) connected to the switch and along with the suction temperature probe local to the
controller the superheat is calculated. Please note that RDM recommended that the evaporator in temperature
probe is fitted as the controller will use this to calculate the superheat in the event of a communication loss
with the Mercury Switch. Setting parameter “Evap Select” to “Remote” allows for the use of this remote
temperature provided by the Mercury Switch. Please see the Mercury Switch user document (PR0018-PHI) for
further details.
Maximum Operating Pressure (MOP)
Maximum Operating Pressure (MOP) support added to Brooklands Controller. MOP is a remote command sent
from the Mercury switch (PR0018-PHI) to the controller to either close or reduce the EEV valve opening when a
predetermined pressure is reached. This MOP value is configured in the Mercury switch setup. When the
Mercury Switch generates a MOP alarm the controller reduces the maximum valve opening (Div Value) to this
percentage. For example if the “Div Value” parameter is set to 50% and the MOP alarm is generated then the
maximum valve opening will be limited to 50%. Therefore as the controller pulses the valve the maximum the
valve will open to is 50%. For Mechanical Valve Controllers the LLV is closed for the MOP alarm duration.
