Technical description
Rated current I_N, hold current I_H
The current rating of the applicable load at its rated voltage should
be set between 0.1...3.1 A. The holding current of the load is internally
adjusted to 60 % of the set current rating. This holding current can
be measured by means of a voltmeter connected to the 2 mm current
measuring plugs (current-proportional voltage: 1 V ^{^=} 1 A).
Setting the current rating
The current rating is set by means of a rotary switch (switch
setting 0 A - 1 A - 2 A) and a 270° potentiometer (setting range
between 0.1...1.1 A). The sum of the two settings should equal the
current rating of the load.
Example: 24 V load with I_N = 1.5 A
Setting: switch 1 A + potentiometer 0.5 A
Technical description
Operating voltage U_B
The max. operating voltage of the SSRPC is approx. DC 60 V. The
min. operating voltage required for 24 V solenoids depends on the
overall ohmic resistance in the load circuit. The switch-on current is
reduced by:
- the voltage drop on the load cable
- the load resistance increasing with the operating temperature of
the load.

Faulty setting of current rating
The red LED (failure indication) blinks in the event of a faulty setting.
The load is disconnected only after approx. 15 sec if the current rating
value is not corrected and the red LED will be permanently lighted.
The load capacity is no longer ensured when the minimum operating
voltage falls below U_{B min} = 28 V. The RED LED (fault) will indicate
and the output will be switched off. Only when an operating voltage
of 29.4 V is exceeded will the load be switched on again and normal
operation status is restored.
Reset is only possible by switching on again.
The tolerance range, in which faulty setting will not be indicated, is
approx. ± 30 % of the holding current.

Maximum operating voltage U_{B max}
The load capacity is no longer ensured when the max. operating
voltage U_{B max} = 60 V is exceeded. The RED LED (fault) will indicate
and the output will be switched off. Only when the operating voltage
falls below 57 V will the load be switched on again and normal opera-
tion status is restored.

Switch-on current I_E = pickup current
The output transistor connects the operating voltage to the inductive
load until actual switch-on of the solenoid (pickup current). After this
period the load current is set back to holding current I_H.
