PROGRAMMING and OPERATION
Programming configures:
• Count to Add or Subtract
• Reset to automatic (Auto ON) or manual (Auto OFF) - see below
• Relay contacts to NO or NC
• Delay (i.e. relay contact ON time) between 0.1S and 9.9S in 100ms intervals
• Decimal point to 3 decimal places
The operation of the output relay under the different programmable configurations is
described in the table below.
Auto = OFF
Auto = ON
4
Count = Add
Operates when the up count reaches the
preset value. Remains latched until
reset. Count continues uninterrupted and
rolls over to 0 when it reaches 999999.
Reset occurs and relay operates
immediately the up count reaches the
preset value. Relay remains operated for
the duration set as Delay time. Resets
the count to zero and operates again the
next time the count reaches the preset
value.
Output Relay
Contacts
SPST voltage free contacts
programmable as NO or NC.
Contact Rating
250Vac @ 8A cosØ= 1
250Vac @ 5A cosØ= 0.4
30Vdc @ 5A cosØ= 1
Reaction time
<20ms.

Count = Subtract
Operates when the down count reaches
zero. Remains latched until reset.
Count rolls over from 0 to 999999 and
continues uninterrupted.
Reset occurs and relay operates
immediately the down count reaches
zero. Relay remains operated for the
duration set as Delay time. Resets the
count to preset value and operates
again the next time the count reaches
zero.
