Introduction

In August 2003 Brivis introduced the new 3 series Contour cooler and also a lesser featured contour was also introduced called the Brivis Profiler.

The Brivis Profiler cooler was introduced to offer a budget model Contour to meet market demand. The Brivis Profiler looks very similar to the Contour with its sloping base, but slight changes have been made to the decorative panels. The Brivis Profiler cooler is also slightly smaller in height than the Contour.

Brivis Contour Brivis Profiler

Both models, Brivis Profiler and Contour, now use the N-E5 control box instead of the older N-E4. The main difference in the N-E5 control is the removal of the isolating switch from the top of the control box. This isolating switch has been relocated to the underside of the cooler so that the power can be isolated without removing the front pad. There has also been some software changes to the N-E5.

Brivis Advance

The Brivis Advance was introduced in 2005 and is designed to take the place of the AD range of units up to Model AD56. However, the AD76 and AD86 will remain in production.

In essence the Advance is a square shaped Contour/Profile, which sits upon the same base frame as the Contour/Profiler. So for the purpose of servicing, all the electrical and operational components are the same and therefore all the information contained in these manuals is relevant.

The BASE is square and sits on a vertical dropper box similar to the AD units, except that the dropper box should come with outwards turned flange so that the locking brackets on the unit attach to the dropper box. Like the AD unit, the cooler should be located high enough on the roof to prevent the back from touching the roof.

The PAD FRAMES are attached in a similar fashion to the Contour and Profile unit. The front and rear pads can be removed by first lifting the roof assembly, and then lifting the pad assembly out; the same way the Contour and Profiler work.

The SIDE PAD FRAMES are slightly different and involve the pad frame being rolled into the centre of the unit and then being raised out. It is important that the pad frame is not forced, as this could damage the alloy brackets.

The ROOF ASSEMBLY also remains the same as the Profiler/Contour units.

Some standard features differ between the Brivis Profiler, Contour and Advance.

Retrofitting the Service N-E5 to 0, 1 & 2 Series Contours.

The service N-E5 control can be used as a replacement control for all previous model coolers, however some parameters need to be adjusted in order for the control to operate correctly. The table below details all of the parameter adjustments that need to be made for each model cooler when fitting an N-E5 into an older model Contour. These parameters are located in the cooler service parameter section, and can only be accessed by using a Networker.

N-E5 Cooler Control Dump Delay Parameter.

Units affected:

All Version 3 Contours and Profiler coolers using N-E5 electronic controller.

Reason for change:

R&D have informed us of a change within the N-E5 service parameters. which has the potential to cause a problem. This change has happened mid production and has affected the first 2020 units. The problem has occurred to service parameter 01, which relates to the Dump Delay time. The change is with the way the parameter is read. Usually the parameter unit was in single minutes, but on the newer N-E5 controllers it has been changed to units of 10 minutes.

For example

- Normal setting was 60, meaning 60 minutes before the cooler would dump.

- New setting is 6, meaning 6 lots of 10 minutes which equals 60 minutes.

If service parameter 01 on the newer N-E5 is changed to 60 when we service these units, it will then dump after 10 hours (60 x 10 minutes = 600 minutes). Vice Versa if Parameter 01 on the first version N-E5 is set to 6, it will then dump after 6 minutes.

In both cases this will cause a fairly major upset with the units normal operation. We can trace the individual controllers by their serial number. The first 2020 controllers have the dump delay setting units in minutes, and the rest of the production controllers will all have the dump delay setting units in lots of 10 minutes.

N-E5 Serial Numbers - 18764 020 0000 to 18764 020 2020 have the dump delay in single minutes.

N-E5 Serial Numbers - 18764 020 2021 and Beyond will have the dump delay setting in lots of 10

minutes.

N-E5 - Version 9, 9a & 10 will have the dump delay setting in lots of 10 minutes.

N-E5 Cooler Control Upgrade

(This issue (2) replaces previous versions of servicing instruction #23 (issue 1))

Units affected: 3 Series Contours and Profilers.

Background: The version 7 N-E5 (original control) has proven to be unreliable, with the majority of

failures occurring with the Servo-seal action. The Version 8 N-E5 was introduced to fix this problem. A tracking problem then started occurring on the trident water sensor. This coupled with lengthy fill problems (software related) caused the units to operate OK for 2/3 hours before blowing hot air. R&D have introduced the version 9 N-E5 control, which has had modifications done to the software. This has improved the failure rate on the Servo-seal (further enhancement from the version 8), and water level control problems, including refill times, have been rectified. Unfortunately the version 9 also suffered from Servo-seal failures, albeit few in number.

Root cause analysis has since proven that the cause of Servo-seal failures is due to power spikes degrading PCB components. The version 9A is the latest N-E5 control, which has been upgraded to protect components from power spikes. Field tests have already proven that the version 9A N-E5 is very reliable.

The Version 9A controllers can be identified by the marking "9A" on the box.

Action: Technicians, when attending any 3 series cooler (Brivis Profiler or Contour), need to

complete these steps: Identify the version of controller in the cooler and replace all N-E5 controls (version 7, 8 or 9) with the new version "9A" controller. Version 8 controllers will be marked with an "8" on the box, and version 9 controllers with a "9", while any version 7 and before will have no marking on the box.

Correctly label the control box with a defect sticker marked "TO BE REWORKED".

Test cooler for correct operation.

Trident Water Sensor Tracking Problems

Units affected: All Contours 1,2 & 3 Series, and Profiler 3 Series.

Background: It has been found in the field that the trident water sensor can be subject to false

sensing. This is caused by mineral build up behind the water sensor probes. The cooler may run for a period of time before the fault occurs, but the fault will eventually result in the pump cavitating because the unit has failed to fill. The build up on the probes forces the electronic controller to think the water level is OK, when in actual fact it doesn't really know at what level the water is at.

Action: Service technicians are required to perform this action when attending any 3 series Contour or Profiler. This action should only be performed on 1 or 2 series Contour coolers if they exhibit the above symptoms. The installation of a modified water sensor should be carried according to the installation instructions.

Plastic Housing Modified Sensor

Installation: Modifications have been made to Trident water sensor to help prevent this electrical

tracking on the water sensor. The plastic legs on the trident probe housing have been removed, preventing any build up of minerals at the low point of the probes (see pictures).

Remove the old water sensor from the cooler trough and attach a defective label to part. This part should be sent to warranty returns. if the unit is under warranty. If the unit is not under warranty this part is to be charged to the customer. Replace the water sensor with Part - 18066 - WATER SENSOR ASSY CONTOUR L1, ensuring that the plastic housing has been modified (see picture above). Test cooler for correct operation.

Documentation: These notes should be included on your POD invoice.

Introduction of 5.5 litre ELBI solenoid

Background: On the 23/11/2004, the 5.5 litre ELBI solenoid was introduced into production for all 3

series Contours and Profilers. it was originally brought into production to try and prevent units from failing to fill during a water limp error. it was found that the cause was not the limited flow (4 litre ELBI) of the original solenoid but a water sensing issue. However the supplier of these solenoids had already delivered 10,000 5.5 - litre solenoids, thus they were used in production.

Action: The introduction of the 5.5 litre solenoid is not expected to make any dramatic change to the coolers operation. However there is a slight increase of water hammer occurring on the premises. Tests conducted by our R&D department have proved that the hammer spike generated by the 5.5 litre ELBI is no greater than our previous 12 litre soft close solenoid. Technicians can identify the new 5.5 litre solenoid by a blue label that has been placed on the side of the solenoid valve body.

INSTALLER COMMISSIONING INSTRUCTIONS

Wiring the Cooler to the Networker

The first step is to run a twin wire cable (i.e. figure 8 cable - 0.75mm2) from the Cooler to the Networker.

Next, mount the Networker backing plate. Remove the backing plate from the Networker by un-clipping.

Be sure to draw the wires from the wall cavity, and feed them through the centre opening of the wall plate. Then mount the wall plate on the wall.

Connect the cable to the Networker connection lead terminal block at the Cooler, and to either the top two terminals or the bottom two terminals on the Networker Backing plate. If these two pairs of terminals are mixed around the Networker will not function.

Networker

If the Cooler is integrated with a Brivis MPS or Auto EMS heater(s), then simply connect the wiring in parallel with the heater's circuit to the Networker.

Installing Multiple Coolers on the Network

The Networker is capable of controlling multiple evaporative coolers on the one system.

When more than one Cooler is installed on a Networker, each Cooler must be given a

different specific identification number, starting at No. 1, and each Cooler must also be designated to a zone (refer to the Networker - Advanced Programming

Manual).

First, complete the installation and wiring of all the units, as described on page 23. Each Cooler must be powered and configured individually, whenever any Cooler identification number is to be changed.

Isolate the power from all other coolers and Network appliances, other than the unit which the identification number is being changed, and proceed to make the change at the Networker wall control through the Installer Set-Up program as follows:

•

Turn the Networker OFF (ON/OFF button).

•

Press the Clock key to enter "Clock Set-Up" program.

Now simultaneously press and hold the 2nd & 4th keys for 3 - 5 seconds, until the screen changes to display:

E01 ID07 :1

Unit Number Parameter Number Parameter Value Eg- Evap cooler number 1 Eg- Number seven Eg- Setting of 1

Note: This is the view on the N-C3 Networker.

•

Rotate the circular dial to change the parameter value displayed at the top left of screen, to the unit number required for this Cooler.

E01 ID07 :2

Unit Number Parameter Number Parameter Value Eg- Evap cooler number 1 Eg- Number seven Eg- Setting of 1

Note: This is the view on the N-C3 Networker.

•

Press the Networker ON/OFF button and exit the program.

•

Turn the power supply at the Cooler OFF, to save the new identification

number.

•

Repeat the sequence for each Cooler, then follow the Networker Advanced

Programming instructions to allocate the Coolers to their respective Networker zones.

Installing dual Networkers on a system

The new Networker N-C3 now allows two Networkers to be installed onto the one system.

When installing two Networkers on a system, they must be wired in parallel to the system; they cannot be wired in series as they will not function correctly. The Networkers are not polarity sensitive.

Both Networkers must be identified individually so that they can communicate together. One of the Networkers must be the master and the other must be the slave. On a dual Networker installation the Master Networker always stores all of the installer and service parameters, and all of the customers settings eg. Programming and clock settings; The Master Networker can be identified by the CLOCK key, when the Networker is in the OFF position.

Note: Only the Master Networker can access the installer or service

parameters.

There is only one room temperature set point, which can be adjusted on either Networker. An Adjustment that is made on one Networker is immediately reflected on the other Networker.

Once each Networker is given its specific Networker ID number or address (Master=1 or Slave=2), they can be assigned to operate the zones according to difference between the sensed temperature and the set temperature. Every Zone must be assigned a Networker for temperature control, The Master Networker is the default Networker for every zone. However this can be altered to the most appropriate Networker (e.g. Networker: 2 = Slave).

A new parameter has been added to the Networker zoning parameters to allow for this Networker Zone assigning.

Installing dual Networkers on a system

Follow these procedures when configuring the two Networkers. The two Networkers must be configured as master or slave. The Networkers should never be configured as both masters or both slaves as the system will malfunction. Because all Networkers come set as masters by default, only the Slave needs to be addressed. Method 1 can only be used if both Networkers are masters. Refer to method 2 if the Master and Slave Networkers are to be reversed, or if both Networkers have been set to Slave by mistake.

Method 1 (new installation).

•

Connect both Networkers to the appliance and power the system up. At this stage both Networkers will be set as Masters, so both Networkers should have the word "clock" next to key 5 (while in the off position). The system should not be operated in this state as there will be communication errors.

•

Determine which Networker you wish to be the Slave.

•

On the Networker you wish to be slave, push the clock key. The message “Clock setting mode.” should be displayed.

•

After the message has finished, ensure the time on the display is flashing. Press keys 2 & 4 for 5 seconds until the message "Installer parameter access." is displayed.

•

By pushing the Mode key, this will move through the different appliances attached to the system (e.g. Cooler/Heater/Networker). Push the Mode key until the screen display looks like this.

Unit Number Parameter ID Number Parameter Value Setting.

n01 ID00 :1

Networker ID Networker Address parameter Address setting 1=Master 2=Slave

•

Using the rotary dial, change the parameter value to 2 (2=Slave).

•

Push the On/Off key to exit.

•

The unit should then be ready for zone configuration.

Dual Networker Configuration: (cont.).

Method 2.

•

Remove the Slave Networker off the backing plate so that the controller is powered down.

•

Press and hold keys 3 & 5, then place the Networker on the backing plate ensuring keys 3 & 5 are still depressed. Continue holding keys 3 & 5 for five seconds after the control is placed on the backing plate.

•

After holding keys 3 & 5 for five seconds, release the two keys. The screen should now scroll this message “Set this Networker’s address!” If the message does not appear please repeat the resetting procedure.

•

After the message has finished, the screen should look like this. Now the parameter value for setting Master and Slave addresses can be set.

Once this parameter value has been set, push the ON/OFF button to exit this Installer set-up program.

Note: All networkers come configured as masters by default. Two masters cannot be connected to one system otherwise the system will not function properly. Similarly if both networkers are set as slaves, the networkers will lock out and will not be accessible. If this has been done, the resetting procedure needs to be performed again to rectify this problem.

Cooler Parameters

N-E5 Installer Parameter Descriptions:

Unit ID Number - Installer Parameter 07 - This is where the unit can be assigned a

different unit ID number for multiple cooler installations. See section on Installing Multiple Coolers on the Network.

Installer Flush Count - Installer Parameter 14 - This is the number of filling operations, between the high and low water sensors, due to the evaporation of water during operation, before the tank will be flushed to dilute the salt build up. This parameter allows the installer to increase occurrence of the flush operation if necessary. The installer cannot decrease the units flush operation above every 20 refills.

Dump Check - Installer Parameter 16 - This parameter was provided so that the cooler Dump-valve and Winter-seal operation could be checked instantly upon installation. By setting this parameter to 1, the cooler will instantly perform a dump and close the Servoseal, and after the normal delay times it will then resume normal operation. This dump function will only occur once, upon power up of the unit. This means if the parameter is left on 1 the cooler will perform its dump check then resume normal operation, but if a power interruption occurs the unit will immediately perform another dump check. The results of leaving this setting on 1 is the possible chance for extra long start up time, because the cooler will initially open the Servoseal, then close the Servoseal and wait for the usual dump time to elapse before opening the Servoseal again and performing the normal start up procedure.

N-E5 Service Parameter Descriptions:

Riser Close Delay - This is the time delay in minutes from when both the fan and the

pump stop operating until the Servoseal closes and the drain tube lowers to drain the tank water. See servicing instruction 21 in the front of this manual.

Fill Time - This is the time in minutes, from when the water inlet solenoid opens and water must be sensed on either of the water level probes, before a lockout will occur.

Min Speed / Max Speed - These are the adjustment parameters, to vary the minimum and maximum fan RPM from the default settings as per the N-E5 model selection. It is not possible to set the minimum speed higher than the maximum speed, and vice versa.

Model Selection Number - Model selection number should be set as per spec sheets information.

Short Dry Pad Time - This is the time in minutes, the pump can be OFF and the filter pads not wetted, before a Pre-wet will be required.

Service Flush Count - This is the number of filling operations, between the high and low water sensors, due to the evaporation of water during operation, before the tank will be flushed to dilute the salt build up. Service technicians can adjust the occurrence of the flush operation if necessary.

Short Pre-wet Time - This is the Pre-wet time in seconds, that occurs if the pump has been OFF longer than the Short Dry Pad Time, and less than the Long Dry Pad Time.

Long Pre-wet Time - This is the Pre-wet time in seconds, that occurs if the pump has been OFF longer than the Long Dry Pad Time.

Long Dry Pad Time - This is the time in minutes, the pump can be OFF and the filter

pads not wetted, before a Long Pre-wet will be required.

Aquasave - The Aquasave is a standard feature on the 3 series Contours. The Aquasave is wired directly into the N-E5 base connector. The parameter settings are 1=Aquasave present, 0=No Aquasave.

Flush Time - The time the solenoid is open during a flush service operation.

Cooler Operation

General Operation

When the Networker is turned OFF, or is in a mode other than "Cooler", then the Contour Cooler will have the ServoSeal closed (Contours only), and the tank drained, provided the unit has been in the OFF condition for longer than 60 minutes.

When the Networker is turned ON in Cooler mode, no function will occur until the Networker signals the Cooler to operate, i.e. the ServoSeal (Contours only) will remain closed and the tank empty.

If either the fan or the pump is required to operate, then the ServoSeal (Contours only) will be driven open, before any other activity can run. The ServoSeal has a direct linkage to the drain valve, and the drain valve closes as the ServoSeal opens, and vice versa. Profiler Models do not have the Servoseal installed, but the drain valve will operate off the same mechanism.

The ServoSeal opening delay time is 20 seconds.

On completion of the ServoSeal opening and drain valve closing action, if the Networker calls for the pump to operate, the water inlet solenoid will be energised to open, and the tank will begin to fill with water.

The N-E5 module will not permit the pump to be energised, until the water has reached the high water level, on the Trident water management system.

After pump commencement the water level will possibly drop below the High level on the Trident water sensor, so the inlet solenoid will remain open for another 10 seconds.

If the Cooler pump has been OFF longer than 2 minutes the Cooler is programmed to automatically Pre-wet the filter pads when the pump is turned ON, before the fan can start operating for both Networker Auto and Manual modes.

This is to ensure in all circumstances the filter pads reach full saturation and optimum cooling potential when the fan starts.

The automatic Pre-wetting time of the dried filter pads, will depend on how long the Cooler's pump has been OFF, as follows:

Cooler Operation:

(cont.)

Networker Control in Auto Mode

The following sequences are normal operation in Auto mode, with the Networker at a set comfort level, and the room temperature varying according to the Cooler's operation and load conditions.

When the Networker is turned ON in Cooler Auto mode, an immediate signal is sent to the cooler to indicate if the unit is required to operate or not.

If the comfort level setting is adjusted on the Networker when operating in Cooler Auto mode, an immediate signal is also sent to the cooler.

Whenever the Networker sends an OFF or ON signal to the N-E5 module, both the pump and the fan will be turned OFF or ON, however, their operation may be delayed by the fill and Pre-wet functions.

The Cooler will be turned ON, if the room temperature is 0.50C. higher than the set comfort level, and OFF if the room temperature is lower.

The ON fan signal from the Networker accompanies a fan speed signal, to determine the speed required according to the temperature differential between the room

temperature and set comfort level.

The fan will operate at minimum speed, when the room temperature is up to 10C. above the set comfort level, and is incremented to be at maximum fan speed, when

the room temperature is 50C. or more above the set comfort level.

During normal operation, at 5 minute intervals, the Networker updates the N-E5 module on the temperature differential between room temperature and the set

comfort level, and if the temperature has varied by 0.50C. or more then the cooler is adjusted.

However, if the temperature changed rapidly by 2.50C. or more within the 5 minute update interval, then the Networker will signal the N-E5 module to adjust

immediately.

If the room temperature is higher than the set point when the Networker is turned ON, then the fan will immediately operate at the speed according to the set point, following the normal ServoSeal, water fill and Pre-wet operations.

Networker Control in Manual Mode

When operating the Cooler in manual mode, the Networker screen changes to display a pump and fan button for manual selection.

The rotary dial is used to select the constant fan speed.

The Pre-wet times apply to manual mode, in the same way described for Auto mode.

However in manual mode, the Pre-wet period can be extended by simply operating the pump longer without the fan.

Fan only operation is available for air movement in high humidity climate conditions, or for ventilation and air circulation.

NOTE: Should the pump be turned ON whilst the fan is operating, then the fan will be forced OFF for the Pre-wet period, then come back ON again automatically.

Wash Service

When the Networker is turned OFF, at the end of use, or the pump and fan have been OFF for more than 60 minutes, the ServoSeal closes (Contours) and the drain valve lowers to drain the tank water.

Following the ServoSeal closing, the Cooler will automatically perform a tank washing action, after the time delay allowed for closing the ServoSeal ServoTime (20 seconds).

A further 45 second delay (WashWaitTime) allows time for the tank to be drained completely, and initially wash out any sediment from the tank.

With the drain valve still in the lowered position, the water inlet solenoid is opened for 30 seconds (WashTime), allowing clean water to further flush sediments from the tank base.

On completion of the wash, an additional 45 second delay applies, before any other (new) operation can be performed i.e. Networker turned back ON again.

The Cooler then remains idle until the Networker is turned ON again, and calls for cooling.

Flush Service Operation.

Since the introduction of the Aquasave water treatment module on Contours, the flushing frequency is different between Contour and a Profiler models. The Contour flush service parameter is set to 250 while the Profiler flush cycle is set to 20. This means the Profiler will flush more often than the Contour cooler.

The N-E5 module program performs a tank flush at regular intervals, to dilute any salt and sediment build up as the unit is operating.

The flush service will not affect the normal pump, or fan functions of the Cooler.

The flush service timing is determined by the number of times the water has filled to the Trident High Water Level Sensor, and then evaporated down to the Trident Low Water Level Sensor.

After 20 tank refills, the Flush Service commences.

Each sequence of 20 or 250 refills of the tank, will force another the flush service operation, although the time between each Flush Service can vary, according to the conditions and Cooler settings.

When the water level evaporates down to the Low Water Level Sensor for the 20th tank re fill, the water inlet solenoid will open and fill the tank to the high water level, then remain open for a further 200 second period.

The water level will continue to rise above the High Water Level Sensor, and over flow out the drain valve / overflow pipe.

The action of the fresh water entering, mixing and overflowing out from the tank, dilutes the salt and sediment ratio back to the original supply water condition.

Aquasave Operation:

(Contours Only).

The Aquasave water treatment module was designed to reduce the requirement for flushing, thus saving water. The module introduces oxidants into to the trough water through a diffuser ball. These oxidants then prevent the growth of bacteria and microorganisms in the water.

The Aquasave module will only operate when the pump is operating, and has an internal timer that will cycle the Aquasave on and off. The timer is set to cycle the unit 7 minutes on and 7 minutes off.

The module has an internal air pump which draws the air though a filter located under the front of the cooler trough. This air then passes through a high intensity spark where the air is filled with oxidants. There air then passes through a tube to the diffuser ball which should be submerged beneath the water.

N-E5 Electronic Control Module Operation

The N-E5 module controls all the Cooler's working operations, using the signals from the Networker sent on a 2 wire bus network. The N-E5 will communicate with the Networker about the status of the Cooler's operation, including malfunction errors.

The N-E5 can be fitted to any 3 series Contour and Profiler Cooler models, but will require configuring to the model type, using the service parameters accessed through the Networker.

The power supply input and output terminals to the N-E5 module, are via the base terminal connection mounting bracket. The module is correctly located into the mounting bracket via side slide rails.

The N-E5 module no longer has a isolating switch on the control box itself. There is a new isolating switch that is located under the front of the cooler allowing the power to be cut to the unit without removing the front filter pad. This isolates the output power supply to all components within the Cooler.

There is a new service N-E5 control box which has a switch located on the top of the box - this is for retrofitting the control into previous model contours.

WARNING: The incoming 240 Volt power supply is not isolated using this switch,

and therefore some terminals within the Cooler will remain energised, until the main power supply on the unit's 3 pin plug and lead, has been disconnected.

Wiring connections direct to the N-E5 module are, the Networker connection loom, the motor speed sensor and the water level control looms. All installer and service parameter access is done through the Networker wall control.

Speed Feedback

The fan motor is fitted with a speed sensor which signals the motor RPM back to the N-E5 Cooler control. The N-E5 must have a speed sensor fitted and operating or the unit will operate in a FAN LIMP mode. The sensor is fitted to the special stub shaft provided on the motor and uses a light beam across the shaft flat section to register the revolutions of the motor's shaft.

The purpose of the sensor is to:

•

Detect if the fan motor (impellor) is rotating when the power is first applied to the fan motor.

•

Detect if the fan motor is locked.

•

Detect if the fan motor is not rotating within the correct operating range.

If the N-E5 doesn't receive any signal from the speed sensor, or looses the signal, the N-E5 will adopt a FAN LIMP mode operation.

Initially, when the motor is required to run and the speed signal is lost, the fan will immediately increase its fan speed and may be driven to the maximum power for a short time prior to commencing the Fan Limp Mode.

Then the FAN_LIMP mode will commence, however, there will be a 4 minute delay before the error is displayed on the Networker (where available).

If the condition rectifies itself, and the speed sensor signal is restored, then the Cooler will resume normal fan operation.

Fan Operation:

(cont.)

DC Brake

Whenever the fan motor is required to operate, the N-E5 uses the motor speed sensor to checks if the motor is rotating.

This rotation of the fan and motor, may be due to air up draught in the dropper duct, whilst the unit was not running.

The N-E5 will apply a brake to stop the rotation by energising the motor with DC Voltage. This is to ensure the fan motor will not be energised and driven in the reverse direction.

DC power will only be applied to the motor, if at the time the fan motor is powered, the motor has not been previously powered for at least 10 seconds, and that rotation is detected above the minimum RPM requiring the brake.

The DC brake will then remain ON until the motor speed sensor registers the fan motor has slowed to a RPM not requiring the brake, before powering the motor for a normal start.

The rate that the DC brake is applied, is a factory setting, and cannot be field modified.

If the fan is operating in FAN_LIMP mode, then the DC brake will not be applied. Allow for the 4 minute delay period to register the error on the Networker, before the DC brake is disabled.

Pump Operation

The Contour Cooler's pump has a synchronous motor with thermal protection, and a magnetic coupling drive to the pump impellor.

The pump impellor may be driven in either rotation direction, which lessens the likelihood of the pump blocking. The pump base is integrated into the tank base and should not require removal.

The pump will be turned OFF for 15 seconds at 15 minute intervals, to allow the water head in the feed tube to the distribution spreader to back flush the pump, and keep it clear of blockages. Additionally, if the pump had an air lock, this pump stoppage will allow water into the pump, to resume normal operation again.

All servicing and maintenance can be done through the service access compartment.

Water Inlet Solenoid Operation

The Contour Cooler has a 240 Volt water inlet solenoid on the under side of the base, at the high side of the roof.

The water inlet solenoid has a flexible hose attached with a filter inserted in the hose connections at each end. A 3/4" to 1/2" BSP nipple is provide for the installer for a convenient connection to the hose.

The water inlet solenoid is assembled in a bracket to support the pipe connection and the outlet discharge, which is direct to a fitting moulded into the Cooler base on the high roof side.

The wiring loom to the water inlet solenoid is concealed under the base, and feeds back into the service access compartment.

Note: The water inlet solenoid uses the water supply pressure to it's diaphragm in the closing action of the valve. Ensure the solenoid closes within 5 seconds of turning the 240 Volt power OFF to the water inlet solenoid.

Dismantling

•

ServoSeal and Drain Valve Operation

Contour and Profiler Coolers have a new and unique mechanism, to drain and empty the Cooler's tank and simultaneously close off the duct (Contours only), at the end of use.

The ServoSeal is a set of adjustable louvers constructed in the Contour's base, which are driven closed and prevent heat loss from the building, when the unit is not in use.

An electric motor drives a linkage that opens and closes the louvers. This motor has another lever that operates at the same time, to raise and lower a flexible drain outlet tube.

When the ServoSeal closes the dropper duct, the drain outlet tube is lowered to a position that all the tank water is naturally drained from the Cooler. The Profiler cooler only has the Drain valve connected to the Servo motor.

The motor that drives both the ServoSeal and drain linkages, is 240 Volts controlled through a geared cam shaft and switch.

The motor is powered to open on one switch circuit, and powered to close on another.

The cam shaft causes the switch contacts to open, stopping the motor and mechanism at the correct position, whether the motor is to be driven forward or reverse.

Trident Water Management System

The Contour Cooler's tank water level is regulated, by turning ON and OFF the water inlet solenoid as required, according to the operating conditions.

After the initial filling, at which point the water inlet solenoid turns OFF, the Cooler looses tank water volume due to evaporation, in the normal course of the unit's operation.

The rate of water evaporation is dependant on the current climatic conditions, the Cooler's operating fan speed and the condition of the filter pad material. All of these of course are infinitely variable.

The water management system uses 3 stainless steel probes, to detect the water level within the tank. The mid level probe is the common low voltage output. The shortest probe is the high water level. The longest probe is the low water level.

The switch function of both version are the same, however, the revised version design has the common voltage output probe, at a closer position to both low and high level probes.

Page 78

Service Manual 32 – Contour 3 Series, Profiler & Advance – Approved Issue 5 Printed 2/13/2014 11:50:17 AM

Trident Water Management System

Trident Operation

When the Networker is turned ON, and the cooler is required to start from an empty tank, the pump is delayed until the tank has sufficient water for it to operate.

As the tank fills, the water eventually makes contact between the Common Water Sensor probe and the Low Water Level Sensor probe, at which point the pump can start operation (Pre Wet).

When the tank fills to the high water level, The N-E5 switches OFF the water inlet solenoid.

During the course of normal operation, with the water inlet solenoid closed, the tank water level is evaporated down to the low water level.

The water contact between the Common Water Sensor and the Low Water Level Sensor probes becomes open circuit.

The N-E5 will then switch on the water inlet solenoid again to refill the tank to the high water level.

The N-E5 module is programmed as part of the overall control, if the expected water levels are not achieved within designated times, then the N-E5 will go to water level limp mode operation.

As the water level control probes will be constantly subjected to water and electrical power during normal operation, it is expected that a coating will eventuate, depending on the water quality.

Trident Water Management System

(cont.)

Abnormal Operation

Water Limp Modes

The Trident water management system will automatically adopt a controlled operation, if it detects the malfunction of the sensing probes, or detects water in the tank when it's not expected.

There are 4 water management errors modes, and these operation modes are communicated to the Networker to indicate the malfunction.

Low Water Level Sensor (failure) - Error 40

High Water Level Sensor (failure) - Error 41

Drain (operation failure) - Error 42

Water Sense Failure (both low and high level sensors) - Error 50

Water Limp mode errors 40, 41 and 42, do not require the cooler to be shut down, but the coolers filling and flush operation is time controlled.

These errors (where available) will only be displayed during the time the water inlet solenoid is open and will alternate between the error screen and the normal display.

The N-E5 module will delay, for 4 minutes, any Limp mode error display at the Networker, just in case the error rectifies itself.

Should the Limp mode condition correct itself, then normal operation and function times will be restored.

Error 50 is different and will cause a lockout, but provides the user the facility to reset the operation at the Networker. However, if the condition is still present after reset, the unit will lockout again.

Networker Error 42

Drain - Failure to drain tank once the ServoSeal is closed (cont.)

Operation sequence on start up cycle:

If the closed circuit on the water sensors has not cleared on the next start up of the cooler, then the Cooler operation will commence as follows:

•

ServoSeal opens and drain valve closes (20 seconds).

•

The Water inlet solenoid will open provided the water level is not already at the High Water Level Sensor (closed circuit).

•

The pump will start operating because the Low Water Level Sensor indicates water is at a sufficient level for the pump.

However, if both the Low and High Water Level Sensors have failed short circuit, then the Low Water Level Sensor failure will be forced after 120 minutes of pump operation. Error 40 code will be displayed, alternating with this drain error, when and if the water inlet solenoid is open.

Because both the Low and the High Water Level Sensors are closed circuit, the water inlet solenoid will remain closed.

As the water inlet solenoid will not open, the coolers tank will not fill, and/or any water that was present will eventually evaporate.

This condition will not harm the pump, but will result in poor and inadequate cooling performance.

To rectify this condition, refer to Service Checks section.

Trident Test Procedure & Service Checks

The N-E5 has a 14 Volt output to the Trident water sensing probes. This voltage can be measured between the Common and the High and Low Level Water Sensors in a dry tank. With water contact between the probes, the voltage drop across the Common and the Low and High Water Level Sensor probes varies, depending on the quality of the tank water.

Dry Tank Test:

With the tank empty of water

•

Check for 14 Volt across the Common (black) Water Sensor probe and the Low Water Level (white) probe.

•

Check again for 14 Volt (with no voltage drop) across the Common (black) Water Sensor probe and the Low Water Level (white) probe whilst gently wiggling the Trident loom plug and connection on the N-E5.

•

Check for 14 Volt across the Common (black) Water Sensor probe and the High Water Level (red) probe.

•

Check again for 14 Volt (with no voltage drop) across the Common (black) Water Sensor probe and the High Water Level (red) probe whilst gently wiggling the Trident loom plug and connection on the N-E5.

Refer to diagrams on pages 75 and 76.

If less than 14 Volts:

•

Check the Trident wire loom and loom connections.

•

Check the Trident loom for continuity.

•

Check the N-E5 Trident connection for 14 Volt output.

•

Check the N-E5 8 Amp fuse is not open circuit.

•

Check for N-E5 PCB track fracture adjacent Trident plug connection (may be intermittent).

Flush-service Guide Table

The higher the quality of the water supply to the cooler, the more tank refills Cooler can operate before a Flush-service will be required.

As the water quality also varies the Wet Test voltage readings, the appropriate Flushservice cycle may be individually set to that water quality.

The following table is a guide to the Flush-service cycle rates based on the entering water supply quality. The voltage reading should be based on the initial fill of the tank, when using this guide.

The voltage may vary between the Low and High Level Water Sensors, so average the 2 voltage readings.

Dealing with Problem Installations

Excessive External Noise from Unit

Check the ducting system for any restriction or sizing error, that would contribute to higher than recommended back pressure on the fan. Note the dropper duct take off sizes and details of the main, branch ducts and outlet diffusers.

Assess the installation requirements in regard to the maximum airflow, to determine if the fan maximum speed can be reduced, without compromising the effectiveness of the system.

Use the Networker service access to adjust fan as required.

Excessive Internal Noise from Unit

Outlet Air Noise:

Check to see if the correct unit size has been selected for the application.

Use the sizing guide factor for the locality, and the type of Cooled area to determine the unit size, as per table below.

Dealing with Problem Installations

(cont.)

Calculate the volume of the individual areas the Cooler's outlets are serving. The locality factor is used to multiply by the room volume, to determine the correct minimum duct and register sizes.

Check that the duct and outlet sizes selected, are capable of delivering the total output of the Cooler selected, as per the minimum recommended size tables.

Duct

Capacity

Outlet

Capacity

Duct Size Cooling

Airflow

Size (mm) Airflow

Capacity

250 mm 150 L/s 250 X 250 Up to 100 L/s 300 mm 275 L/s 300 X 300 Up to 250 L/s 350 mm 425 L/s 350 X 350 Up to 375 L/s 400 mm 600 L/s 400 X 400 Up to 500 L/s 450 mm 990 L/s 450 X 450 Up to 600 L/s 500 mm 1080 L/s 550 mm 1230 L/s 600 mm 1420 L/s

If the room and/or the area air requirement calculation is less than 85% of the Cooler's maximum output (midway between the minimum and maximum Output Selection figure), then the duct and outlet sizes should be increased to meet this level.

Page 93

Service Manual 32 – Contour 3 Series, Profiler & Advance – Approved Issue 5 Printed 2/13/2014 11:50:17 AM

Dealing with Problem Installations

(cont.)

Check if the unit selection is excessively over sized, which would require the duct and outlets to be significantly upgraded to carry the additional air quantity of the Cooler.

The Cooler Selection Chart can be used as a reference in this respect, for the calculation of minimum sized ducting and outlets to upgrade to.

Operation Noise:

•

Check that the ducting has not been damaged or restricted.

•

Check the dropper duct has been secured to the roof timbers, or supported sufficiently, so as not to transfer vibration through other structural members of the building.

•

Check the water pipe and wiring (conduit) is not transferring vibration to structural members of the building.

•

Check the duct and fittings are insulated.

•

Check the Cooler is not transferring excessive vibration onto the dropper duct of the buildings structure.

Dealing with Problem Installations

(cont.)

Condensation:

Condensation in evaporative systems may be a result of the humidified air from the outlets, passing over a surface that has a temperature cool enough to condense the vapour suspended in the air, onto the cool surface. An example of this is an outlet air stream directed onto a refrigerated cabinet in a shop, or moist air contacting a cool tile floor surface.

In most cases, the concentration of the air from the outlet is the main contributing factor for the condensation, therefore it is advisable to redirect the air stream.

Condensation may also result from excessive humidity, due to either the current climate conditions, or that the conditions have changed rapidly, cooling the room air that has a high humidity or water vapour content.

Excessive humidity may also be a result of an inadequate exhaust area.

Make sure enough window and/or door area is open, for the unit to work correctly. The table below shows a guide to the amount of opening required, for effective cooling for each model.

Water Entering Building

When dealing with the problem of water entry in a building, it is often difficult to ascertain the water source, due to water tracking and capillary action.

The following checks relate to both Cooler faults and installation faults:

•

Check the Cooler's base and trough is not damaged.

•

Check the Cooler is installed level and the overflow pipe can function correctly.

•

Check the water distribution system is not blocked causing incorrect / excessive water to pads or water tracking.

•

Check the operation of the filter pads and ensure there is no water lift off.

•

Check the flashing of the dropper duct, water supply pipe, electrical conduits and drain pipes for leakage.

•

Check internal water pipe and drain pipe lines and fittings for leakage.

•
