EBME Forums Forums Maintenance Service Manuals & Schematics Hill-Rom Affinity II Service Manual

dear friends,

as you know, hill-rom affinity II is a maternity bed. i was searching the manual for up-down motor breaking system. because when i lift up the bed by command, itself get off. i have thought maybe it was a motor problem. i have inspected the motor but there wasn't any abnormal condition (120 v AC Motor). whereupon i have searched on the internet about monophase asynchronous motors breaking systems. i find out the breakings system working by dc voltage applied to auxiliary windings of the motor. i have inspected again the applied voltage on motors there wasn't dc voltage. this cause the bed get off itself.

now, i think motherboard or motor driver board defective. but i already need service manual.

thanks.
