Manual Drive Operating Instructions
Isolate all sources of energy to prevent safety hazard due
to unexpected motion. System design and operating
procedures must ensure that the drive will have no
unintended motion that can create a hazard to personnel when operating
the drive manually. This includes electrical energy turning the motor as
well as energy stored in a vertical load or spring.
There are two manual drive options available on the Tritex, Hand
Wheel (HW) and Side Drive (SD)
The hand wheel option includes an internal switch that is closed when
the hand-wheel drive is fully disengaged and opens when an attempt is
made to engage the hand wheel drive. This switch is in series with the
actuator overtemperature sensor to form a combined run permissive
signal. When manual drive is engaged, an Actuator Overtemperature
fault occurs. The fault action for this fault will disable the drive.
This function is not safety rated, so is not usually sufficient to ensure
safety. Power to the drive must be isolated before manually operation.
The Side Drive does not include and interlock switch so power must
be removed before use.
Important information to avoid damage to the manual drive
If manually driving with a brake engaged or high force is
necessary, please consult Exlar Application Engineering.
If a power tool is used to operate the manual side drive the
speed should be limited to 600 RPM
An impact driver should never be used to operate the manual
side drive.
Determine end of stroke of actuator or system and do not apply
force past it.
Refer to Table 1 for maximum torque specifications.
