Manual tripping
(Electrical contacts/wiring test)
Note:
On controls with LP and/or HP man. reset, push corresponding
LP and/or HP man. reset knob during tripping.
Trip:
use FINGERS ONLY! (Do NOT use screwdriver)
To resume control operation after safety cut-out,
push man. reset knob as indicated.
Note:
LP man. reset is possible only after system pressure
has risen above cut-in value.
HP man. reset is possible only after system pressure
has dropped below cut-out value.
Manual reset
Convertible reset
Insert a screwdriver into the slot on the lock disc and turn
it to desired reset conguration. Do not turn the screw
on the lock disc as it may damage the convertible reset
mechanism.
Note:
Do not select automatic reset if safety of the system requires
manual reset.
Note:
Selected reset conguration may be protected against
unauthorized actions applying a seal.

Adjustment
Note:
Remove lockplate before adjustment.
Replace lockplate after adjustment (if desired).
1. Adjust range spindle
to desired CUT-IN value.
2. Adjust dierential spindle to desired
DIFFERENTIAL (DIFF.) value.
CUT-IN minus DIFFERENTIAL
equals CUT-OUT
Example: Example:
CUT-IN equals CUT-OUT plus
DIFFERENTIAL
CUT-OUT minus DIFFERENTIAL
equals CUT-IN
1. Adjust range spindle
to desired CUT-IN value.
2. DIFFRENTIAL (DIFF.) is xed.
Value printed on scale plate.
1. Adjust range spindle
to desired CUT-OUT value.
2. DIFFRENTIAL (DIFF.) is xed.
Value printed on scale plate.
CUT-IN – DIFF. = CUT-OUT
30 psig – 10 psi = 20 psig
(2.1 bar) (0.7 bar) (1.4 bar)
CUT-OUT+ DIFF. = CUT-IN
12 psig + 10 psi = 22 psig
(0.8 bar) (0.7 bar) (1.5 bar)
Example:
CUT-OUT– DIFF. = CUT-IN
203 psig – 58 psi = 145 psig
