Issue
Satchwell ALM series Linear Actuator requires replacement.
Environment
Satchwell ALM series Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF Series Plug and Seat Valve Body.
Satchwell ALM series Linear Actuators.
Cause
Obsolescence of Satchwell ALM series Linear Actuator.
Resolution
Replace Satchwell ALM series Linear Actuator with MV15B-230 Linear Actuator and Linkage Kit and wire as follows :-
ALM = MV15B-230 + L7SV (880-0126-000) Linkage Kit.
Actuator wiring :-
ALM Terminal Number 1 = MV15B-230 Terminal Number Y2
ALM Terminal Number 2 = MV15B-230 Terminal Number Y1
ALM Terminal Number 3 = MV15B-230 Terminal Number N
N.B.
ALM power consumption = 4.5 VA MV15B-230 power consumption = 12 VA operating and 15 VA Transformer sizing
Should the Satchwell ALM series Actuator include a wired Auxiliary Switch (ALA1211) then the following Accessory should also be installed on the MV15B-230 Actuator as appropriate and should be wired as follows :-
S2 - MV15B = Two independent 250 volt 10 amp / 3 amp rated SPDT Auxiliary End Point Switches.
Auxiliary Switch wiring :-
ALA1211 Terminal S1 = S2 - MV15B Switch 1 Terminal C
ALA1211 Terminal S2 = S2 - MV15B Switch 1 Terminal B
ALA1211 Terminal S3 = S2 - MV15B Switch 1 Terminal A
ALA1211 Terminal S4 = S2 - MV15B Switch 2 Terminal C
ALA1211 Terminal S5 = S2 - MV15B Switch 2 Terminal B
ALA1211 Terminal S6 = S2 - MV15B Switch 2 Terminal A
