Locking Solenoid Adjustment
The configuration of the head locking solenoids can be changed from fail safe on power failure to fail
lock or vice-versa in both directions of rotation, by re-adjustment of the component parts,
Figure 4.11 - Solenoid Detail
Note - If the fail state of the solenoid is changed by physically turning it around then parameter
0.0. MUST be altered to suit.
Direction A Direction B 0.0. Value
BMT (fail lock) BMT (fail lock) 00
SMT (fail safe) BMT (fail lock) 01
BMT (fail lock) SMT (fail safe) 02
SMT (fail safe) SMT (fail safe) 03
Warning -
Fail lock solenoids become hot during operation since they are energised until
released.
For fail safe units check :
1. With solenoid de-energised and plunger extended by action of the spring the locking pawl is
held clear of the baffle plate outside diameter. Adjust the position of solenoid coil if necessary,
with the head in home position, retract the plunger manually, and the locking pawl will engage
in the recess on the ratchet block without excessive friction. On release pawl will also swing
clear.
2. Energise the solenoid, the pawl will engage the recess in the ratchet block. De-energise the
solenoid and the pawl will release clear of baffle plate outside diameter.
3. Re-energise the solenoid and the locking pawl is engaged in the ratchet block. Manually
operate the locking pawl to the Release Position against the force of the energised solenoid.
There will be some resistance but it must not be excessive. Adjust the position of the solenoid
coil to reduce resistance to a minimum and re-check as detailed above.
