The Belimo Code

This article is taken from a flyer written by Belimo about four years ago called “The Belimo Code” We thought we would revive the article to help our clients remember or for the newbie’s to learn from. This article will cover most of the Belimo actuators you will see in the field, for the others, give us a call and we will “Break the Code” for you.

The first part of the Belimo code is why Belimo? Belimo is a Swiss company so the name Belimo is derived from its Swiss meaning…

BEraten                Consulting

LIfern                    Delivering

MOntieren             Mounting

Now that we have the Belimo name code “cracked” lets breakdown the actuator codes…The first letter of the actuator code is all about TORQUE…

G             360 in-lb              G= GIANT

A             180 in-lb               A=AWESOME

A             133 in-lb               A=AWESOME

N             90 in-lb                 N=NORMAL

L              35-45 in-lb            L=LITTLE

T              18 in-lb                 T=TINY

The second letter of the actuator code is about MOTOR ACTION…

F=SPRING RETURN (on power failure the motor will return to its normal position)

M=NON-SPRING RETURN (on power failure motor will stay in its current position)

The third letter is about motor speed…note: non-spring return actuators can combine a forth letter to designate MOTOR SPEEDS…

Q=Quickest running                        (non-spring return)

C=Fast running

A=No Position Feedback              (spring return only)

No Letter= Normal Speed

B=Basic

X=Customized

Next will be a set of numbers…These numbers are about POWER SUPPLY…

24=24 VAC/DC

120= 120 VAC

230= 230VAC

After the POWER SUPPLY numbers (stick with me) are the CONTROL letters/numbers…

Blank=On/Off (spring return)

-1= on/off (non-spring return)

-3= Floating Point (spring return)

-3= On/Off, Floating Point (non-spring return)

-3-P5= On/Off, Floating Point with 5Kohm Feedback (non-spring return)

-3-P10= On/Off, Floating Point with 10Kohm Feedback (non-spring return)

-SR= 2-10 VDC

-PC= 0-20 volt (Phasecut)

-MFT= Multi-Function Technology (program what you want)

-MFT95= 0-135ohm

-MFT-20= 6-9 VDC 20 VDC power supply (spring return)

At last we have our last letter which will deal with actuator OPTIONS…

-S=Built in auxiliary switch

-T= Terminal Block

Blank=Cable Version

We have now broken ‘THE BELIMO CODE” until Belimo introduces more actuators, then we may need to add to our code breaking article. If you need Belimo actuators give us a call at Stromquist and Company @ 1-800-241-9471(Atlanta) or at 1-800-638-7828 (Florida)and we will be “Code Breakers” together.
