Notes
1. The QN_J series devices are approved under the Entity Concept
as Intrinsically Safe for Class I, Division 1, Groups A, B, C, & D, Class
II, Division 1, Groups E, F, & G, and Class III, Division 1 Hazardous
(Classified) locations. Under the Entity Concept the parameters
for the QN_J and devices are Vmax=30V, Imax=100 mA, Ci=66nF,
Li=0.80mH. In order to have an approved loop the associated
apparatus (barriers) must be FMRC approved under the Entity
Concept with the following parameters: Voc=40V, Isc=100 mA.
The control drawing for the associated apparatus will specify the
allowed connected inductance and capacitance.
2. Installation of the solenoid and its associated barrier must be in
accordance with the respective control drawings supplied by the
respective manufacturers. This equipment must be approved by
Factory Mutual Research Corporation as Intrinsically Safe for Class I,
Division 1 Hazardous (Classified) locations.
Touch & Tune switch setting
1. Lift bottom cam and rotate until sensor is activated. (White
highlight will be next to sensor.) Release cam and be sure it slides
fully onto spline.
2. Operate actuator to opposite position, push down on top cam and
repeat process.
