Troubleshooting procedure for rod changer
Rod removing (selector mode on S2 position)
Step 1 (Starting position)
the carousel is properly positioned (a rod housing is in front of the opening
of the rod catcher inductive switch Dt3 is activated: the light L is alight)
the rod clamp arms are swung into the carousel
the rod clamps are closed onto a rod (valves Y6 + Y7).
Rod changer control lever moved in K1 direction and hold in position. After 1 sec. delay, then step 2
Step 2
the rod clamps fully open (valves Y5 + Y7) pressure switch S4 closed
and pressure switch S3 opened after clamps opening, then
the carousel rotates (valve Y1) Inductive switch Dt3 is activated, then
the light L is alight, the carousel rotation stops (Y1 off), the rod clamp arms
swing towards the guide (valve Y4) Inductive switch Dt2 is activated, then
valve Y4 off, the rod clamps close onto the rod (valves Y6 + Y7) pres-
sure switch S4 opened and pressure switch S3 closed after clamps closing, then
valves Y6 + Y7 off
Rod changer control lever moved in K2 direction, then step 3
Step 3
the lower rod clamp closes, the upper clamp slightly opens (valves Y5 +
Y8 are activated during temporization of setting 0 (chap 4), then Y5 + Y7 off)
the drifter move forwards (Y27)
the movement speed is controlled (Y46)
the drifter rotation starts (Y32)
Rod changer control lever moved in K4 direction, then step 4
Step 4
the rod clamps open in guiding position (valves Y5 + Y7 are activated dur-
ing temporization of setting 0)
the drifter reverses (valve Y28)
the movement speed is controlled (valve Y45)
drifter reverse rotation starts (valve Y33)
M1 button is depressed while the rod changer control lever is kept in K4 direction, then step 5
Step 5
the rod clamps close onto the rod (valves Y6 + Y7)
Rod changer control lever moved in K3 direction and hold in position. After 1 sec. delay, then step 6
Step 6
the rod clamps are closed onto the rod (valves Y6 + Y7)
the rod clamp arms swing into the carousel (valve Y3) Inductive switch
Dt1 is activated and Dt2 is released, then
valve Y3 off.
