Danger: electrical shock hazard Actiona May 08 Rev 1 Page 2 of 8 GENERAL INFORMATION The M5-3P-CMS (24V) is used to provide control and monitoring of the Actionair Mode 5-3P Control Mode. The unit provides: • Local or external set point control. • Local (LED) status. • Local damper travelling indication, • Local test switches • External Fire ALARM input for damper fail-safe RELEASE. • External set-point override input for damper RESET. • Volt-free outputs indicating SET POINT, RESET and RELEASE status
Operating voltage - 24 Volt ac/dc (ac 50Hz or 60Hz) One M5-3P-CMS (24V) is used to operate one Mode 5-3P control mode only. Actiona May 08 Rev 1 Page 3 of 8 DIMENSIONS Fig 1.Dimensions of M5-3P CMS (24V) INSTALLTION Surface mounting
- Position and level the unit on to suitable flat surface (such as a wall) and use a pencil to mark the mounting hole positions.
- Remove the unit from the wall, drill four appropriate holes for the type of fastening selected to mount the unit.
- Remove back plate (six screws) and safety cover (four screws). Retain screws/washers.
- Ensure that only specified cables are used for interconnection of equipment. a. Max outer cable diameter to suit ferrite and gland 8.5mm b. Max inner core cross sectional area (CSA) to suit terminals 1mm² stranded or 1.5mm² for solid core.
- All cables to be passed through ferrite rings supplied (4off packaged inside unit). Secure ferrites close to gland e.g. using electrical tape or cable tie etc. Note: dependant on wiring configuration not all ferrites/glands may be used. Unused glands leave blanking plug in situ.
- Connect as per wiring detail on inside face of back plate. Unit MUST be earthed but other optional connections may be omitted.
Check and set PCB jumper setting to suit internal or external SETPOINT requirement (default is internal). 240mm
RESET RELEASE 65mm 120m 240mm Actiona May 08 Rev 1 Page 4 of 8
- If external release (fire alarm) option not used then ext release terminals MUST be linked.
- Replace safety cover and back plate.
- Fix unit securely to wall using appropriate fixings.
Ensure all cables are routed safely. Avoid sharp bends. Fig 2. Mounting of the unit onto the wall Important Note: The Mode 5-3P PTC control mode is for 3 position setting, i.e. RESET, RELEASED & one SET POINT. It is not for modulating on a continuous basis. The third position could be changed externally once or twice on a daily basis for night set back or boost, but should be limited to this , as otherwise wear may result causing the damper unit to be unable to fulfil its life safety function at some point in the future. VAV type systems should still be addressed with a control damper in line. 4off fixings to attach unit to substrate Actiona May 08 Rev 1 Page 5 of 8 WIRING Ext. 2−10Vdc ADJUST (−ve) Ext. 2−10Vdc ADJUST (+ve) RELEASE Indication (vfc) RELEASE Indication (vfc) RESET Indication (vfc) RESET Indication (vfc) SET POINT Indication (vfc) SET POINT Indication (vfc) Ext.

The NON-ETR Control Mode version has 4 signal wires, whilst the ETR version has 6 wires, two of which (nos 3 and 5) are not used and must be isolated. CAUTION Ensure that all wiring is correctly completed before applying power! Do not connect/disconnect wires when the unit is powered. Do not unscrew the unit from the wall when the power is on. Actiona May 08 Rev 1 Page 6 of 8 Fig 3. Front panel details OPERATION (refer to fig. 3) Note: - Allow time for damper to travel to set positions (up to 150 seconds). Applying power to the unit will move the associated damper to the SET POINT (5) (set by external input (2-10VDC) or TRIM potentiometer (6)) providing the Ext. RELEASE contact is closed. Two push buttons (7&8) are provided for testing. Each button should be held until the damper reaches the desired position as indicated by the relevant LED illuminating (1or4). Pressing both buttons at the same time will cause the unit to travel towards the RELEASED position. HINT: The SET POINT may be “chased” by using the test buttons to set an airflow releasing them, and then adjusting the TRIM potentiometer until the SET POINT LED illuminates. The buttons must be released otherwise the LED will not illuminate. When the damper reaches the SET POINT the green LED illuminates. There are two additional LEDs, one red (4) to indicate fully RELEASED, and one yellow (1) to indicate fully RESET. Two additional small red LEDs (2&3) indicate that the unit is trying to move towards RESET or RELEASED. Either of these will remain illuminated until the SET POINT is reached. (In the case of overriding or testing, one of these will illuminate in the opposite direction to which the unit is actually moving and will remain illuminated until the unit returns to set point. The damper will only spring return to the RELEASED position if: The power is lost, “Ext. RELEASE” contact becomes open circuit, Or the ETR fuse /test switch operates. Test that the unit functions as per your requirements.
RESET RELEASE 1 7 6 8 2 5 3 4 Actiona May 08 Rev 1 Page 7 of 8 Local TRIM potentiometer is a 17 turn device that turns infinately at each end of the range. First 3 turns of each end have no effect on adjustment. Anticlockwise rotation moves the control mode towards RESET. Fault Finding NOTE: It is possible to have RELEASED and SET POINT LEDs illuminated simultaneously at control voltage of 2 to 3V, due to Control Mode end switch tolerances. Similarly the same applies for RESET from 9 to 10V input. If the unit does not function as expected, the following table will provide suggested actions:- Fault Suggested action No indication is shown on unit. Check 24V supply is connected to unit. Check Mode 5-3P Control Mode is correctly connected to unit. Unit shows RELEASED indication With no SET POINT indication with control I/P Check PCB jumper setting. Check Ext. RELEASE contact closed. [link if not used]. Check Control Mode. If External 2-10V adjust option is used check external voltage is > 2V. If internal TRIM option is used, rotate TRIM anti-clockwise until set point illumates. Unit shows RESET indication With no SET POINT indication If External 2-10V adjust option is used check external voltage is < 10.0V. If internal TRIM option is used, rotate TRIM clockwise until set point illumates. Damper permanently RESET Check Ext. RESET contact open. COMMISSIONING / MAINTENANCE The unit is maintenance free, and contains no serviceable parts. The M5-3P CMS (24V) should be commissioned and is recommended that it is tested annually as follows: • Check operation of controller/damper system via pressing and holding Reset and Release push buttons independently and observing LED status and damper blades travel to test position. • Remove the Ext. RELEASE input to the unit to check status and that damper fully closes. Actiona May 08 Rev 1 Page 8 of 8 • Reinstate Ext. RELEASE and damper returns to set point position. • Light cleaning of surface of unit using a damp cloth. Do not to allow moisture to penetrate unit. Do not use any form of solvents. • The attached damper should also be subject to regular operational checks, cleaning and lubrication (as instructed by the manufacturer) in accordance with local requirements or 12 monthly intervals.
