PINOUT SCHEME FOR SPECIAL DESIGNS
Control cable for external temperature control:
-
digital signal (PWM 10-24 V
DC
max. cycle time 1 se-
cond)
+ = brown
- = white
Control cable for external potentiometer for temperature or
speed control:
Control cable for external speed control:
-
digital rpm= 15V
DC
, l/max = 10mA; PMW/1-
10KHz/50-100% (50% minimum air-flow)
-
analogue 5-10V
DC
; (5V
DC
= minimum air-flow)
+ = green
- = white
Warning:
For analogue and digital speed control, the minimum air-flow must be guaran-
teed when
the hot-air blower is running.
Signal line for external speed indicator:
-
1 impulse per revolution
-
open collector exit
+ = brown
- = white
Compensating line for 'K' type internal thermocouple:
+ = green
- = white
