Wiring On/Off, 24V, 120/230V

SY Actuator Wiring Diagram, SY1…5-24 – On/Off SY1…12-110 (220) On/Off

Observe class 1 and class 2 wiring restrictions.

Transformer sizing = SY actuator draw X 1.25 (safety margin)(Ex. SY2-24 requires 3.0A x 1.25 = 3.75A, 3.75A X 24 VAC = 90VA Transformer).

Indicates an action or condition that may cause irreversible damage to the actuator(s) or associated equipment.

Equipment damage!Power consumption and input impedance must be observed.

CAUTIONIndicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Warnings and Cautions appear at appropriate sections throughout this manual. Read these carefully.

Hazard Identification INSTALLATION NOTES

W546

NOTES SY1…5-24

Each actuator should be powered by a single, isolated control transformer.

• Isolation relays must be used in parallel connection of multiple actuators using a common control signal input.• "H" cannot be connected to terminal #3 and #4 simultaneously.

• Required: Terminal #7 needs to be field wired to enable heater circuit.

SY MFT ActuatorsQuick Troubleshooting Guide

Verify that Control Signal and Power are present at the actuator.• Measure between Control Signal + and – and power + and – on

control board. (See photo of control boards below for locations).• Check fuses on both boards. If fuses are blown, replace before

proceeding.

Verify that the green LED is lit on the control board – this indicates power is present.

If yes:• Push the button labelled “Adaption”, hold for 3-5 seconds then

release. (see left photo for 24V, right photo for 120V)• The LED next to green LED should light up (amber in color)• Actuator should click. Drive fully in one direction. It will stop there

for 5-10 seconds. Click and drive fully in the opposite direction.• The amber light should go out.

If the sequence does not happen as above, please have the tech make a note of what does happen.

Possibilities include• Amber light goes on, actuator clicks but does not move at all.• Amber light goes on, actuator clicks and drives in one direction, and

clicks but does not drive in the other direction.• Amber light does not light, and the actuator does nothing at all.

If something else occurs, please make a note and communicate to a Belimo Technical Support Representative as the actuator most likely will need to be replaced.

If the actuator adapts correctly:1. Verify correct wiring of control signal (confirm correct polarity of

field wiring and meter). Must have “Control +” and “Control –” and not share the “Control –” with the 24V common, or 120V Neutral (4 wires are required, 2 for power and 2 for Control Signal).

2. Provide a DC control signal other than minimum or maximum (suggest 6 VDC or 50% command).

3. Measure with DC voltmeter on “Control +” and “Control –” at actuator and verify that a voltage other than 0(2) or 10V is present on those terminals. If actuator does not drive to approximately the mid position and voltage is present, the actuator most likely will need to be replaced.

The following information is helpful to determine warranty coverage and additional steps that might need to be taken:1. PO# or Belimo SO# or ID# (ID is located on actuator cover under

the model #).2. Is this a retrofit or was it factory assembled to a valve?3. Has this actuator ever worked on this site (brand new install that

did not work, or has been working correctly for a certain period of time).

4. Proper transformer sizing (see PGPL for current VA requirements).5. Confirm correct wire size vs. length or run for SY actuators.
