Wiring
Besides power input and interlocking, there are several connector terminals available that can be
used to incorporate the capsealing system into other control wiring. The interconnection wiring
diagram appears on page 32. At the end of the manual there is a complete system schematic
diagram.
AC input
- The system should be connected to a 120 VAC or 240 VAC, single phase, power
source depending on the model provided. An appropriate cable and plug will be provided from
the factory. Refer to page 32 for the connection diagram.
Customer interlock
- These terminals can be used to stop the capsealing system. For the unit
to run, a maintained contact closure is required across these terminals. When the contacts open,
the unit will stop. Once the contacts are closed again, the START button must be pressed to
resume operation. If this functionality is not required, a jumper must be placed between these
terminals.
Temperature switch interlock
- These terminals are used to monitor the operation of the
cooling fan in the coil. A temperature switch is connected here. If the coil temperature rises
above the normal operating temperature, the capsealing system will turn off. The temperature
switch is a required element of the control circuit and must not be bypassed.
Auto-start
- A contact closure across these terminals will enable the auto-start feature. This
feature could be used to put the capsealing system into a standby mode when the conveyor
system stops. When the conveyor starts again, the capsealing system will resume operation
automatically.
When the contacts are closed, the capsealing system will be in a ready condition. The START
button is pressed and the unit runs. If the contacts are opened, the capsealing system will stop
delivering power to the sealing coil, but will not shut off. When the contacts are closed again,
operation will resume, if no fault condition exists.
If the customer interlocks are opened, the capsealing system will shut down completely. To
resume operation, the interlocks must be satisfied, the auto-start contacts closed and the START
button pressed.
