6.3 GUARD INPUT

Enables or inhibits command signal input on both Analog and raise/Lower models.

6.4 ANALOG OUTPUT

Function:	Current feedback signal tracks the output of
	the Remote Set Regulator. Signal is typically
	used to telemeter pressure output value back
	to the command site.
Range:	4 - 20 mA common ground type output
Load Resistance:	380 Ohms Max.

6.5 ACCURACY - ANALOG MODELS

Electrical Input to Pressure Output: ±5% of span

Pressure output to Feedback:

±5% of span

6.6 ACCURACY - RAISE/LOWER MODELS

Feedback Volts to Pressure Output:	±5% of span
Pulse Input to Pressure Output:	±20% of span
6.7 DC POWER
12 Volt Model:	11 - 14 Vdc @ 0.35 A Max.
24 Volt Model:	22 - 28 Vdc @ 0.25 A Max.
Fuse:	1 A, 250 Vdc, 3AG
6.8 STEPPER DRIVE MECHANISM
Stepper Motor:	Gearing from motor shaft to pressure
	regulator assembly results in approximately
	22,000 incremental steps for 100% output
	range travel.
Output Rate of Change:	Full scale sweep adjustable from 1.8 to 69.4
	minutes.
Environmental Effects:	±1.0% Max. full scale per 50°F (28°C)
Supply Voltage Effect:	±0.15% Max. full scale per 1 volt change
