Contact settings

4.2.1 MVAX 11 (Unit RL
With the armature closed onto a 0.25mm (0.011") feeler gauge the make contacts should be
closed, but should be open using a 0.38mm (0.015") feeler gauge.
Force to just close the break contacts:
Force to just open the break contacts:
Contact gap:
4.2.2 MVAX 12, MVAX 21, 31 (Unit RL
With the armature closed onto a 0.25mm (0.011") feeler gauge the make contacts should be
closed, but should be open using a 0.35mm (0.013") feeler gauge.
With the armature closed onto a 0.75mm (0.029") feeler gauge the break contact should be
open, but should be closed using a 0.8mm (0.031") feeler gauge.
Force to just close the make contacts:
Force to just open the break contacts:
Force to just lift the fixed contact off its support:

Note:
4.2.3 MVAX 21 (Unit RL
With the armature closed onto a 0.25mm (0.011") feeler gauge the make contact should be
closed, but should be open using a 0.35mm (0.013") feeler gauge.

Mechanical flag settings

4.3.1

Hand reset reverse flags

With the armature closed onto a 0.45mm (0.018") feeler gauge, the flag should be free to
fall, but should not fall using a 0.35mm (0.013") feeler gauge. Adjustment is made to the
catch spring on the flag.
4.3.2

Self reset reverse flags

Adjust the flag operating lever such that the flag side arm is parallel to the frame, when
viewed from the side and the flag covers the flag label.

On MVAX 21, 31 Relays - To measure the force to just close or the
force to just break on the lower right hand contact when viewed from
the front of the module, it is necessary to carefully lift the upper
moving contact blade to remove the pressure on the lower contact.
