Control Board - Pentax IPFC-Serie Betriebsanleitung

Control board

Analog inputs (10 or 15 Vdc):
1. AN1: 4-20 mA: sensor 1
2. AN2: 4-20 mA: sensor 2
3. AN3: 4-20 mA / 0 - 10 Vdc (settable
by jumper C.C.): external set
4. AN4: 4-20 mA / 0 - 10 Vdc (settable
by C.C.): trimmer for frequency
regulation / external set 2
Digital inputs:

IN1 : motor start & stop

IN2: value set 1 & 2 switching

IN3: sensor 1 & 2 switching

IN4 : motor start & stop + alarms
reset

0V
We recommend using only no voltage
contacts.
Opening or closing the digital contacts
(depending on software configuration
set (see IN/OUT. parameters) you can
start or stop the motor.
