Issue
Satchwell ALi series Linear Actuator requires replacement.
Environment
Satchwell ALi series Linear Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body.
Actuator type :- ALi series.
Cause
Obsolescence of Satchwell ALi series Linear Actuator.
Resolution
Replace Satchwell ALi series Linear Actuator with S-E M800 Linear Actuator and Linkage Kit :-
ALi = M800 + L2SV (880-0124-000) Linkage Kit.
N.B.
Should the Satchwell ALi series Actuator include a wired Auxiliary Switch then the following Accessory should also be installed on the S-E M800 Actuator as appropriate :-
S2 - Two independent 24 volt 4amp AC-1 rated SPDT Auxiliary End Point Switches. (880-0104-000)
Particular care should be taken when selecting an S-E Forta M800 Actuator to replace an existing Satchwell ALi series Actuator.
The S-E Forta M800 Actuator may be used to replace an existing Satchwell ALi series Actuator but it should be noted that where an existing Satchwell ALi 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 Forta M800 Actuator (50VA) will also be required. (e.g. S-E Transformer Type TR60)
Where an existing Satchwell ALi 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 ALi series Actuator (16VA) only.
In such circumstances the existing independent Transformer will also require replacement by another independent Transformer, rated to provide the greater level of power required by a single S-E Forta M800 Actuator (50VA) (e.g. S-E Transformer Type TR60)
