Series 90 Intrinsically Safe Control
Installation, Maintenance
Intended Use
This line of Intrinsically Safe Pressure Control Pilots receives a low current input signal from a variety of machine controllers and
converts the current signal into a proportional differential pressure signal suitable to control larger hydraulic equipment in hazardous
locations. The Intrinsically Safe Controls can be added to a Series 90 pump as a standard option or purchased separately.
Danfoss offers five different models of Intrinsically Safe Pressure Control Pilots to accommodate a variety of standard industrial
process controllers. Various combinations of hydraulic nozzle sizes and coil resistances yields a relationship between electrical current
(input) and hydraulic differential pressure (output).
Refer to the Unit Specifications tables on pages three and four for proper selection.
Installation
Mechanical installation
Ensure that the four supplied O-rings are in place on the bottom of the unit. These pressure control pilots are fastened to the second
stage of the control with four M5 x 0.8 x 16 mm socket head screws. Torque to 5 Nm (44 in-lb).
Electrical Installation
A Mil-Spec Connector (MS3102C-14S-2P) provides the means for electronic signal input to the device. Proper selection of the mating
connector to ensure safe operation in a hazardous environment is required (Recommended MS3108E-14S-S, Danfoss Kit number
K08106). A suppression circuit is incorporated in the PCP torque motor cover but by itself does not insure intrinsic safety. An additional
safety barrier used to connect intrinsically safe circuits with non-intrinsically safe circuits must be connected in series between the
PCP and controller. The safety barrier and electrical controller must be isolated from the hazardous area either through use of a purge
enclosure or mounted in a safe area. The intrinsically safe device enclosure grounding terminal must be connected to a robust chassis
ground. The connection must be in accordance with applicable standards where required.

Putting into service
For instructions on putting a pump with the Intrinsically Safe Control in service, refer to Initial Startup Procedure in the Series 90 Pumps
Service Manual, AX152886483063.
Prior t
o installation, inspect packaging and unit for any damage. Do not continue installation if unit has visible signs of damage.
Danfoss is not responsible for the design of the control input circuit outside of the installed Mil-Spec connector. Proper design
on the entire system as noted in the applicable standards is required for safe usage in hazardous environments.
The condition of use
The EDC is designed to be controlled from a DC current source or voltage source. Pulse width modulation (PWM) is not required. But, if
a PMW signal is used, use a carrier frequency between 200 Hz and 4000 Hz. Do not use a pulse current of more than 120% of that
required for full output(refer to unit specifications below).
