DS 9.03 - M2K03 - Micro2000 Controller
August 2013
Approvals
The
Micro2000
series controllers conform to:
• Electromagnetic emission and immunity requirements according
to standards EN55011 (CISPR11) and EN50082 for CE Marking and
C-Tick Labelling.
Installation
1. The
Micro2000
should be mounted on DIN rail in cabinets
approved for switchgear or industrial control equipment. It
should be mounted in a dry and clean location, free of excess
vibration. Maximum terminal cable entry is 1.5mm² wire.
2. Wire in accordance with INNOTECH connection diagrams and
local bylaws or refer to your local distributor.
3. Connect the 240VAC supply to the correct terminals on the
controller, observing the correct polarity of the connections.
Connect the EARTH to the correct terminals on all units.
4. The maximum wire length between the control station and the
controller should not exceed 50 metres. The wiring between
these devices should not be run in parallel with conductors
carrying high current.
Fault Representation
1. If the Control Station display reads "HELP", this is due to a
communications error between the Controller and the Control
Station. Check the interconnecting 2 core screened cable
for continuity or short circuits. As a result of this failure the
controller will shutdown after 1 minute.
2. If the Control Station reads "SEN FAIL", this is due to an open
circuit room Temperature Detector. To test the detector,
disconnect it from the room and connect it directly to the
controller.
Inputs
1. INPUT 1 Temperature Sensor Input: (Range 5 - 35°C.)
This input is used to read the current temperature.
2. INPUT 2 - Selectable Dry Contact Digital Input:
Using Parameter 14, Input 2 can be either be an AC Fault Input,
a External Disable Input, or a Condenser Water Fault Input.
AC Fault
If "AC" is selected in Parameter 14 and Input 2 is "ON" the
Micro2000
will display "AC FAIL" and continue to operate in it's
current mode. After the fault is rectified, the display will revert
back to its previous state.
External Disable
If "dIS" is selected in Parameter 14 and Input 2 is "ON" the
Micro2000
will shut down all outputs and display "OFF". After
the disable input is removed, the
Micro2000
will continue to
operate in its previous state.
Condenser Water Fault
If "Con" is selected in Parameter 14 and Input 2 is "ON" the
Micro2000
will shut down all outputs except the Fan, display
"Con FAIL". After the fault is rectified, the
Micro2000
will
continue to operate in its previous state.
3. INPUT 3 - Selectable Dry Contact Digital Input:
Using Parameter 15, Input 3 can be either an External
After Hours Input, or a Door Switch Input.
External Afterhours
If "AH" is selected in Parameter 15, Input 3 is used as an
external toggle After Hours switch. It operation is the same as
the
button on the front panel. See Push buttons section
for more information.
Door Switch
If "Door" is selected in Parameter 15 and Input 3 is "ON" for the
time set in Parameter 16 (Door Open Time), then the
Micro2000
will display "Door" and will go into Standby Mode. In
Standby mode the Dead Band is increased by the
adjustable value in Parameter 17 (Door Reset Dead Band). If
Parameter 17 reads 10°C, there is a 5°C dead band either side of
the setpoint. However if Parameter 17 is set to 0 (Off) then the
Micro2000
will shutdown all outputs. After the door is closed the
Micro2000
will continue to operate in is previous state.
All Digital Inputs have a 5 second delay before they are
registered. Except the Condenser Water Fault which has a 20
second delay.
Outputs
Relay #1
Fan (16A Relay. Common and Normally Open Contact)
Relay #2
Heat 1 (10A Relay. Common and Normally Open Contact)
Relay #3
Heat 2 (10A Relay. Common and Normally Open Contact)
Relay #4
Cool 2 (2A Relay. Common and Normally Open Contact)
Relay #5
Cool 1 (2A Relay. Common and Normally Open Contact)
Push Buttons
The normal control button use is described below:
1.
The "Auto" button is used to enable or disable the
programmed schedules. When the Auto "LED" is on the
schedules are enabled, when it is off they are disabled.
2.
This button has three selectable modes of operation.
Normal After Hours
If Parameter 6 (After Hours Adjustable) is set to "Off" ,
pressing the
button will instruct the Controller to run for
the time set in Parameter 5 (After Hours Run Time).
Adjustable After Hours Run Time
When the button is pressed and Parameter 6 is set to "On", the
controller will display the amount of time in hours it will run for.
The user can adjust this time by using the
and
buttons.
The Controller will run for the amount of time chosen after the
button is pressed again or a period of 5 seconds where
no buttons are pressed.
Manual Override
When Parameter 5 is set to "On", the
button can be used
to change the current state of the controller. It can be used
to override any programmed schedules. For example if the
Controller has been turned on by a Schedule, the
button
can be used to force the controller Off until the next scheduled
"On" time. Similarly if the controller is Off, the
button
can be used to force the controller On, until the next scheduled
"Off" time.
If the Schedules are disabled via the
button, the
button has a normal On/Off function.
3.
This button can be used to select either Vent mode (Fan
only runs) or Condition Mode (Full control).
4.
By pressing this button the Current Time will be
displayed for 10 seconds before returning to the default
display. If pressed again then the Current Date will be
displayed for 10 seconds.
5.
The Up and Down buttons can be used to change the
current Setpoint.
This product should only be installed by qualified personnel.
