Electronic Pot 2 Wire Operating Mode

Provides speed Increase and Decrease inputs to allow EPOT operation with 2 wire inputs. The opto inputs can be switches as shown in Figure 3-32 or logic signals from another device. The values of the preset speeds are set in the Level 1 Preset Speeds block, Preset Speed #1 or Preset Speed #2.

Figure 3-32 EPOT, 2 Wire Control Connection Diagram

J4-8 CLOSED allows normal control operation.

OPEN disables the control and motor coasts to a stop.

J4-9 CLOSED starts motor operation in the Forward direction. OPEN motor decels to stop (depending on Keypad Stop mode).

J4-10 CLOSED starts motor operation in the Reverse direction. OPEN motor decels to stop (depending on Keypad Stop mode).

Note: Closing both J4-9 and J4-10 at the same time will reset a fault condition.

J4-11 Selects speed command as defined in the Speed Select Table 3-14.

J4-12 Selects speed command as defined in the Speed Select Table 3-14.

J4-13 CLOSED selects ACC / DEC / S-CURVE group 2.

OPEN selects ACC / DEC / S-CURVE group 1.

J4-14 Momentary CLOSED increases motor speed while contact is closed.

J4-15 Momentary CLOSED decreases motor speed while contact is closed.

J4-16 If J4-16 is connected, you must set Level 2 Protection block, External Trip to “ON” to activate the opto input.

CLOSED allows normal control operation.

OPEN causes an external trip fault. The control will disable and the motor coasts to a stop. An external trip fault is displayed (also logged in the fault log).
