Model 3381 Two-Hand Machine Control Anti-Tiedown Monitor

The 3381 series contains all the anti-tiedown features of the 3380 series, with the addition of adjustable time output. The 3381 series is Pin for pin compatible with 3371 controls.

Series 3381E –  Same as series 3381, but with remote output adjustment capability. The supplied potentiometer should be connected from pin 3 to pin 8. Time ranges are the same as 3381.

Features:

Double force guided output relays – Each relay is checked for proper status prior to beginning a machine cycle.

Control reliable – Series 3380 is designed to meet the OSHA classification of “control reliability” as defined in section 1910.217(13).

Pin for pin compatibility – The 3381 series can be used to replace the 3371 series controls with no modification to wiring.

Operation:

TIMED OUTPUT – Both start switches must be pressed within a fixed time to operate. The load will remain energized until the timer runs out or one or both switches are released.

DELAYED TIMED OUTPUT – This circuit has the feature of time delay. When the two start buttons are activated, the load will stay energized until the timer runs out. However, the timer will not time out while the delay switch is closed. The control will reset if either start switch is released or upon time out.

MAINTAINED TIMED OUTPUT – This circuit has the added feature of maintained output. When the two start buttons are activated and the hold switch is closed, the load will stay energized after the start buttons are released. When the timer runs out, the control will reset.

MAINTAINED AND DELAYED TIME OUTPUT – This circuit has the feature of maintained output in addition to delayed operation. The operation is identical to the delayed circuit above but the control will continue to energize the load even if one or both start switches are released. The control will reset when the timer times out.
