Issue
Satchwell ALX series Linear Actuator requires replacement.
Environment
Satchwell ALX series Linear Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body.
Cause
Obsolescence of Satchwell ALX series Linear Actuator.
Resolution
Replace Satchwell ALX series Linear Actuator with MV15B-24 Linear Actuator and Linkage Kit :-
ALX = MV15B-24 + L7SV (880-0662-000). Note: this part no. is for both actuator and linkage kit.
N.B.
Should the Satchwell ALX series Actuator include a wired Auxiliary Switch then the following Accessory should also be installed on the MV15B-24 Actuator as appropriate :-
S2 – MV15B = Two independent 250 volt 10 amp / 3 amp rated SPDT Auxiliary End Point Switches.
Particular care should be taken when selecting an S-E Forta MV15B-24 Actuator to replace an existing Satchwell ALX series Actuator.
The S-E MV15B-24 Actuator may be used to replace an existing Satchwell ALX series Actuator but it should be noted that where an existing Satchwell ALX series Actuator has been connected directly to a Satchwell Controller, an independent Transformer rated to provide the greater level of power required by a single S-E MV15B -24 Actuator (12VA) will also be required. (e.g. S-E Transformer Type TR32)
Where an existing Satchwell ALX series Actuator has been connected via an independent Transformer, it is possible that the Transformer may have been rated to provide the level of power required by a single ALX series Actuator (3.5VA) only.
In such circumstances the existing independent Transformer may also require replacement by another independent Transformer, rated to provide the greater level of power required by a single S-E MV15B-24 Actuator (12VA) (e.g. S-E Transformer Type TR32)
