These outputs contain PTC Thermistors with a trip rating of 750 mA at 20 °C (68 °F). The PTC Thermistor current pass-
ing capacity must be de
-
rated 10 percent for each 10 °C increase in ambient temperature.
Example:
The ambient temperature where the control panel is used is 30 °C (86 °F).
The outputs will be de
-
rated by 10 percent for the 10 °C increase.
(750 mA) (.90) = 675 mA
Outputs 9 and 10:
24 VDC designated outputs, these outputs are powered directly through the circuit board.
These outputs contain PTC Thermistors with a trip rating of 200 mA at 20° C (68° F). The PTC Thermistor current pass-
ing capacity must be de
-
rated 10 percent for each 10° C increase in ambient temperature.
Example:
The ambient temperature where the control panel is used is 30° C (86° F).
The outputs will be de
-
rated by 10 percent for the 10°C increase.
(200 mA) (.90) = 180 mA

Outputs 1 to 8 are isolated general purpose
outputs. If connecting an inductive load such as
a solenoid or relay a snubber circuit or surge
suppression circuit is required to prevent
damage to the output transistors.
Output 9 is a special output designated to
energize a solenoid coil when the system is in
“Lubrication Mode
.
”
Output 10 is a special output designated to
output a low 20
–
80 cycle per minute frequency
to a solenoid (piston pump solenoid) when the
system is in “Lubrication Mode
.
