The factory SW 4 SW 2 switch settings provide a 1 ms pull in and an 8 2 maintenance cycle These settings are suitable for most applications However special operating conditions such as the use of higher viscosity adhesives gt 2000 cps may require a higher pull in and or mainte nance cycle The SW 4 SW 2 switch banks are accessed by removing the four control panel screws and remov ing the control panel NOTE Adjusting the pull in and or maintenence cycle above the factory settings will change the allowable cycle rate of the M od Plus Electric valve as shown in the table below See the M od Plus Electric Valve service manual for the minimum ON and OFF times IHEEEEEEE Switch Position 12 3 4 5 ar aa PULL IN MAINTENANCE DURATION DUTY CYCLE SW4 controls channel output 1 SW2 controls channel output 2 Switch Position Pull in Minimum Switch Position Duty Minimum 1 2 3 4 Time ms OFF Time 5 6 7 8 Cycle OFF Time off off off off 0 6 off on off on 7 0 off off off on 0 7 off on on off 7 4 off off on off 0 8 off on on on 7 8 off off on on 0 9 on off off off factory setting 8 2 off on off off factory setting 1 0 on off off on 8 6 add 2ms off on off on 1 1 add 1ms on off on off 9 0 add 3ms off on on off 1 2 add 2ms on off on on 9 4 add 4ms off on on on 1 3 add 3ms on on off off 9 8 add 5ms on off off off 1 4 add 4ms on off off on 1 5 add 5ms Minimum OFF Time of M od Plus Electric Valve Page 2 5 I
