5-8. Fail

A fail contact is energized when a fail situation 

occurs. Fail situations are configured in secton 

5-11. For SOFT Fails the contact and the dis

-

play on LCD are pulsating. For HARD Fails the 

contact and the display on LCD are energized 

continuously.

Hard fail only

The contact reacts to Hard Fails Only

Hard + soft fail

The contact reacts to Hard and Soft Fails 

Only contact S4 is programmed as a fail-safe 

contact. This means that contact S4 wil be 

 

de-energized when a fail situation occurs.

5-9. Simulate

The contact can be switched on/off or a 

percentage of output can be simulated. On/Off 

enables the user to manually switch a contact 

on or off. The percentage is an analogue value 

and represents the on time per period.

 

The Duty cyde Period time (see figure 5-4) is 

used as a period for percentage simulation. 

Note that the (simulated) settings of the con-

tacts become visible in measuring mode and 

after HOLD has ended c.q. has been overruled. 

A warning is activated in case of a simulated 

output contact.

5-10. Input contacts

The terminal of the ISC450G provides for an in

-

put contact (see Figure 3-7). This input contact 

can be used to switch the range of the outputs. 

The range can be increased by 1 decade.
