3 HARDWARE
The operation of voltage and current monitors is reflected with the corresponding FlexLogic™ operands (Cont Op # Von,
Cont Op # Voff, Cont Op # Ion, and Cont Op # Ioff) which can be used in protection, control and alarm logic. The typical
application of the voltage monitor is Breaker Trip Circuit Integrity monitoring; a typical application of the Current monitor is
seal-in of the control command. Refer DIGITAL ELEMENTS section for an example of how Form A contacts can be applied
for Breaker Trip Circuit Integrity Monitoring.
Relay contacts must be considered unsafe to touch when the unit is energized!! If the relay contacts need
to be used for low voltage accessible applications, it is the customer's responsibility to ensure proper
WARNING
insulation levels!
USE OF FORM-A OUTPUTS IN HIGH IMPEDANCE CIRCUITS
For Form-A output contacts internally equipped with a voltage measuring cIrcuit across the contact, the circuit has
NOTE
an impedance that can cause a problem when used in conjunction with external high input impedance monitoring
equipment such as modern relay test set trigger circuits. These monitoring circuits may continue to read the Form-
A contact as being closed after it has closed and subsequently opened, when measured as an impedance.
The solution to this problem is to use the voltage measuring trigger input of the relay test set, and connect the
Form-A contact through a voltage-dropping resistor to a DC voltage source. If the 48 V DC output of the power sup-
ply is used as a source, a 500 Ω, 10 W resistor is appropriate. In this configuration, the voltage across either the
Form-A contact or the resistor can be used to monitor the state of the output.
Wherever a tilde "~" symbol appears, substitute with the Slot Position of the module; wherever a number
sign "#" appears, substitute the contact number
NOTE
When current monitoring is used to seal-in the Form-A contact outputs, the FlexLogic™ Operand driving
the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in situ-
NOTE
ations when the element initiating the contact output is bouncing, at values in the region of the pickup
value).
