With the armature closed onto a 0.25mm (0.011") feeler gauge the make contacts should be
clos
ed, but should be open using a 0.38mm (0.015") feeler gauge.
Force to just close the break contacts: 20/25 grams.
Force to just
open the break contacts: 18/23 grams.

.)
With the armature closed onto a 0.25mm (0.011") feeler gauge the make contacts should be
clos
ed, 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 shou
ld be closed using a 0.8mm (0.031") feeler gauge.
Force to just close the make contacts: 20/25 grams.
Force to just
open the break contacts: 20/25 grams.
Force to just l
ift the fixed contact off its support:
15/20 grams.
Contact gap for make and break contacts: 1.75/2mm (0.07/0.08").
Note: On MVAX 21, 31 Relays - To measure the forc
e 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.

2
), MVAX 31 (Units RL
2
and RL
3
)
With the armature closed onto a 0.25mm (0.011") feeler gauge the make contact should be
clos
ed, but should be open using a 0.35mm (0.013") feeler gauge.
Force to just close the make contact: 10/15 grams.

).
4.3 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 usi
ng 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, wh
en
viewed from the side and the flag covers the flag label.
