Fan Pump 3 Wire Operating Mode

Operation in the Fan Pump 3-Wire mode is controlled by the opto isolated inputs at J4-8 through J4-16. The opto inputs can be switches as shown in Figure 3-29 or logic signals from another device.

J4-8	CLOSED allows normal control operation.					Analog GND
	OPEN disables the control and the motor coasts to a stop.	Command Pot or				Analog GND
J4-9	MOMENTARY CLOSED starts motor operation in the Forward direction.	Command Pot or				Analog Input 1
Note:	Closing both J4-9 and J4-10 at the same time will reset a fault condition.		0-10VDC			Pot Reference
				5KW		Pot Reference
				5KW	Analog Input +2
J4-10	MOMENTARY CLOSED starts motor operation in the Reverse direction.				Analog Input +2

					Analog Input -2
Note:	Closing both J4-9 and J4-10 at the same time will reset a fault condition.				Analog Input -2
Note:						Analog Out 1
J4-11	OPEN motor decels to stop (depending on Keypad Stop mode).					Analog Out 1
J4-11	OPEN motor decels to stop (depending on Keypad Stop mode).					Analog Out 2
J4-12	CLOSED selects STOP/START and Reset commands from terminal strip.					Analog Out 2
J4-12						Enable
	OPEN selects STOP/START and Reset commands from Keypad.					Enable
	OPEN selects STOP/START and Reset commands from Keypad.					Forward Run
J4-13	CLOSED allows other selections, see Speed Select Table 3-11.					Forward Run
J4-13						Reverse Run
	OPEN selects speed commanded from Keypad (if J4-14 and J4-15 are closed).

						Stop
J4-14	Firestat. Selects Level 1, Preset Speeds, Preset Speed #1.					Stop
J4-15	Freezestat. Selects Level 1, Preset Speeds, Preset Speed #2 (if J4-14 is closed).					Run Command
J4-15					Speed Command
J4-16	If J4-16 is connected, you must set Level 2 Protection block, External Trip to “ON”				Speed Command
J4-16						Firestat
	to activate the opto input.					Firestat
	CLOSED allows normal control operation.					Freezestat
	OPEN causes an external trip fault. The control will disable and the motor coasts					External Trip
	to a stop. An external trip fault is displayed (also logged in the fault log).					External Trip
