B&C Technologies M720 Dryer Control (DE, DP, DI Series) - Manual (Page 33)

Every controller in a network must be programmed to the same communication speed. In
cases where long cables are used to connect controllers to the network, or in case of difficul-
ties with communication between PC and controller, often a lower communication speed is
necessary. When this parameter is changed, the controller must be restarted.
7. Cnt.reset no pass
If this parameter is set to yes, the counters per program (see Section 4.4.1 on page 19) can be
reset without a password. If this parameter is set to no, password level 1 (1234) is needed to
be able to reset the counters per program.
8. Rotation time-out
If a rotation sensor is defined in the machine configuration (see Section 4.9 on page 35),
this parameter is the time the drum is allowed to turn without a signal from the rotation
sensor. For example, if the value of this parameter is 10, and the drum has been turning for
10 seconds without a signal from of the rotation sensor, the machine will stop and display
an alarm. The value of this parameter is based on when the drum is running at full speed.
If the machine is equipped with a frequency inverter, the time-out value is automatically
recalculated with regard to the programmed drum speed. For example, if the time-out value
is 10 and the programmed drum speed is 50%, the internally calculated time-out value will
be 20 seconds.
If no rotation sensor is defined in the machine configuration, this parameter will not be visi-
ble.
9. Jog drum speed
If jog buttons and a drum with an inverter have been defined in the machine parameters (see
Section 4.9), this parameter is used to adjust the drum speed in case jogging is active. The
value is a percentage of the maximum speed. For example, if 30% is programmed, the speed
of the drum motor in case of jogging will be 30% of the maximum.
If no jog buttons or no drum with an inverter is programmed, this parameter will not be
visible.
10. Heater reset time
Some types of heaters require a reset signal before they will restart after a fault alarm. When a
program is started the output for resetting the heater will be activated (output 1) as standard.
This parameter is the number of seconds the output will be on when starting a program. The
value used will depend on the type of heater (refer to the heaters instructions for this).
11. Blower clean time
When a program is started the output for an optional clean signal (like an air blast) for the
blower will be activated (output 3). This parameter is the number of seconds the output will
be on when starting a program.
12. Blower WYE del.
If the machine is equipped with a star/delta arrangement to start the blower motor this pa-
rameter is the delay for switching the blower star/delta switch from off to on after restarting
the blower.
