1.0 General Information
1.01 Opening the unit
1) To open the enclosure, first remove the snap-in clips at the bottom of the two side
panels: using a flat bladed screwdriver push the clip from below away from each side
panel.
2) Press the release pad on each side at the bottom of the enclosure and lift off each
side panel in turn by first pulling the bottom towards you. This will reveal the four
facia plate fixing screws.

3) Unscrew these four screws and lift the facia plate from the back box, ensuring that the
ribbon cable between the two PCBs has been unplugged at the main PCB end.
Place the screws, snap-in clips, side panels and facia plate in a safe place until the back box
has been fixed, wired and is ready for reassembly and set-up
*Please note if using a CaterSense V2 with inbuilt twin speed control you will
also need to remove the top plate (4) and front control box (5) as shown in the
diagrams below.
* IMPORTANT – Please ensure that when reassembling the CaterSense V2 with
inbuilt speed control unit that both the main power plug and control cable plug
are firmly fitted before powering the unit.

1.02 Fixing details
1.02A For standard control unit:
The CaterSense V2 unit has six (6) mounting holes which can be used (as shown below)
Note: Ensure that the enclosure is mounted on a clean and level surface away from the direct cooking
area or wet surfaces.
1.02B For inbuilt speed control unit:
The CaterSense V2 + ATSC unit has four (4) mounting holes which can be used (see
Diagram 2)
Note: Ensure that the enclosure is mounted on a clean and level surface away from the direct cooking
area or sinks and other wet areas.

1.03 Cable entry
1.03A For standard control unit:
The CaterSense V2 enclosure has an area of 190 x 25 mm which can be drilled for conduit
entry on the top edge of the enclosure.
1.03B For inbuilt speed control unit:
The CaterSense V2 & ATSC has two main areas for cable entry: the top area (223 x 40mm)
and the back of the enclosure (130 x 30mm located at the top).
For ease of installation, most of the connections you will need are made in the enclosure for
the ATSC. The inter-connections between the ATSC and the CaterSense controller are
achieved via two pre-made cable looms.
1.04 Electrical connections
1.04A For standard control unit:
The CaterSense system has two sets of terminals all mounted along the top edge of the main
PCB circuit board.
Terminals 1 to 22 are the smaller terminals (1.5 mm² cable) and are used for the
sensors, inter-locking devices, remote speed and on/off control,
screened cable must be used (we recommend Beldon 8723 but
that should be the choice of the installer and dependant on the
individual installation).
Terminals 23 to 34 are the larger terminals (4 mm² cable) and are for the power
connections for the fans, gas valve and power supply to the unit.
The terminals are of the rising clamp type protection.
All cabling should be kept to the top of the unit within the designated area. No cables should
be placed or laid across the PCBs as this may cause damage.

Remaining Terminals are the larger terminals (4 mm² cable) and are for the power
connections for the fans, gas valve and power supply to the unit.
The terminals are of the rising clamp type with protection.
All cabling should be kept to the top of the unit within the designated area. No cables should
be placed or laid across the PCBs as this may cause damage.
1.05 System set-up
The CaterSense V2 unit has a number of intelligent control solutions. Each of which is set via
a DIL (DIP) switch mounted on the main PCB circuit board. The CaterSense also has a
unique “Self-set” system commissioning tool which makes for easy system commissioning.
These devices are located on the main PCB as detailed in Diagram 3.
2.0 Set-up and Commissioning
The set-up and commissioning of your CaterSense system is in two parts, Initial and
System.
2.01 Initial Set-up
Once all of the wiring has been completed and tested and the system is ready to be set-up
and commissioned, the following sequence MUST be followed to ensure the CaterSense and

* To enable the Electric or Gas Fired Heater Battery Control you must ensure the
jumper J21 is fitted as per image below.
(Jumper J21)
c) Input Jumpers / Sensor Links ON = OFF =
IMPORTANT: Ensure power supply is switched OFF before adjusting input jumpers
or sensor links.
J25 (KNOCKOFF) - If using a remote knockoff circuit in terminals 11 and 12, ensure that
J25 is OFF. Otherwise, ensure J25 is ON.
J23 (FIRE ALARM) - If using a fire alarm circuit in terminals 9 and 10 OR a fan hold-off
thermostat OR thermal cut outs are connected ensure that J23 is OFF. Otherwise, ensure
J23 is ON.
J13 (SINGLE) - If only using one fan, ensure J13 is ON. Otherwise, ensure J13 is OFF.
d) Inter-lock circuits
Ensure that the fire alarm and knock-off switches (if fitted) are all in the operational
position.
e) Gas pressure range
Whenever the system is initialised with the "start" pad, a pipework integrity test is carried
out. This opens the gas solenoid valve for 10 seconds, and then closes the valve for 30
seconds and monitors the pressure. If this pressure drops by 10% or more during this 30
seconds stage, the system will alarm and not start.
When all of the above stages have been
completed, re-assemble the CaterSense
unit by reversing the sequence described
above in section 1.01.
NOTE: Ensure the ribbon cable is plugged
in correctly with the key pin (red stripe) at
the top on the main PCB, and at the
bottom on the facia (see Diagram 5).
Otherwise this may cause damage to the
PCB and the unit will not function correctly.

2.02 System Set-up – CaterSense V2
Once the above has been carried out, the system is ready to be powered up.
Within the step-by-step sequence of set-up instructions the CaterSense unit will give you
feedback on the system via audible “beeps” and coloured LEDs.
Set-up sequence:
1) Activate "SETUP" mode on controller
2A) Manual speed control fan power monitoring set-up
OR
2B) Automatic speed control fan power monitoring set-up
OR
2C) Electronic speed control fan power monitoring set-up
3) CO2 monitoring alarm stages (if required)
4) Heater battery set-up (if required)
5) Demand extract air control set-up (if required)
The sequence detailed above MUST be followed to enable the CaterSense unit to program its
parameters. Ensure that the system is allowed to settle and become stable before moving on
to the next stage. DO NOT RUSH.

2A) Manual speed control fan power monitoring set-up
In this set-up the set-up button can be pressed numerous amount of times to
eliminate accidental or double presses.
Once the air balancing procedure has been carried out, ensure the fans are running. Set each
fan to the lowest speed and allow them to run and settle.
The system will produce a short beep. Change the speed of the fans to the next speed up.
Allow system to run and settle. (If using an analogue speed controller, split the space
between min and max speed into approx 10 equal parts).
Repeat this process until all fan speeds have been saved.
Once this has been successfully completed.
The set-up is now complete and the system is ready to run. However we recommend that the
system is run through the systems checking procedure (2.03) to ensure the unit is
successfully commissioned.

2B) Automatic speed control fan power monitoring set-up
The CaterSense will then display the following.
The fans will start at full speed. Using the and pads in conjunction
with the min and max pots on the ATSC-02-xx PCB ensure that the system has been
correctly balanced, and you have correctly set the minimum and maximum speeds for each
fan.
The ratio pot adjusts the speed of fan 2 relative to fan 1, to allow you to balance the make-up
air with the amount of air extracted.
IMPORTANT: Ensure that you do not set the minimum speed to a level that will cause the
fan to overheat. Trent Products recommend a minimum voltage output to the fans of no less
than 140Vac between the "M" and "C" terminals on the speed control PCB. Consult the fan
manufacturer for more details. Once you have setup the fan speeds, return the fan speed to
maximum by using the ‘B’ button before continuing.

The system will produce a short beep. The CaterSense will slowly reduce the speed of the
fans to establish the characteristics of your system. DO NOT INTERRUPT THIS PROCESS.
After approximately two minutes, the system will have fully recorded the running currents of
