Instrument Input Signal, Output Signal and Failure Mode Selection
The selection of "input signal", "output signal" and "failure mode" is determined by "Dip Switches" S1 to S8.
Instrument Input Signal Selection
A) 4 - 20 mA: Set 1 "ON" / 2 "OFF"
B) 2 - 10 VDC : Set 1 "OFF" / 2 "ON"
C) 1 - 5 VDC : Set 1 "OFF" / 2 "OFF"
Valve Position at Signal Input
A) Fully "Closed" at 4 mA, 2 V or 1 V and fully "Open" at 20 mA, 10 V, or 5 V : Set 6 "OFF"
B) Fully "Closed" at 20 mA, 10 V or 5 V and fully "Open" at 4 mA, 2 V, or 1 V : set 6 "ON"
Valve Position upon Loss of Instrument Signal
A) Valve stays in "LAST POSITION" when 4 mA (2 V or 1 V) is "Fully Closed" : Set 7 "ON" /
8 "ON"
B) Valve moves to "Closed" when 4 mA (2 V or 1 V) is "Fully Closed" : Set 7 "OFF" / 8 "ON"
C) Valve moves to "Open" when 4 mA (2 V or 1 V) is "Fully Closed" : Set 7 "ON" / 8 "OFF"
A) Valve stays in "LAST POSITION" when 20 mA (10 V or 5 V) is "Fully Closed" : Set 7 "ON" / 8 "ON"
B) Valve moves to "Closed" when 20 mA (10 V or 5 V) is "Fully Closed" : Set 7 "ON" / 8 "OFF"
C) Valve moves to "Open" when 20 mA (10 V or 5 V) is "Fully Closed" : Set 7 "OFF" / 8 "ON"
ZERO & SPAN ADJUSTMENT
Zero (VR2)
A) Place actuator in full clockwise position.
B) Input signal (4 mA, 2 V, or 1 V).
C) Turn VR2 in a counterclockwise direction
until RED LIGHT remains ON.
DEADBAND ADJUSTMENT
Deadband (SW1 - SW0 adjust sensitivity to input signals)
A) Greatest sensitivity is with switch "1"
(0 - 90ø is divided into 80 set points)
B) Least sensitivity is with switch at "0". (17 set points)
Thank you for selecting DynaQuip electric actuators for your valve automation requirements.

SPAN (VR1)
A) Place Actuator in full counterclockwise position.
B) Input signal (20 mA, 10 V, or 5 V).
C) Turn VR1 in a clockwise direction until the GREEN LIGHT remains ON.
(Each selected number after "1" drops the number
of inputs by 17 from the previous setting.)
(Setting 2 would have 63 set points, etc.)
