An option of 2 or 4 SETPOINTS, programmable within the full
display range, can be incorporated to the unit thus providing
alarm and control capabilities by means of individual LED
indicators and relay or transistor outputs.
All the setpoints provide independently programmable value,
time delay (in seconds), asymmetrical or symetrical hysteresis
(in counts of display) and selectable HI/LO acting.
The setpoints are also configurable to activate independently
(each one activates at its corresponding programmed value) or
tracking one another (setpoint 2 can be conditioned by the
action of setpoint 1, setpoint 4 by setpoint 3). Such latter
function is included in the programming menus with the name
of TRAC and, in case of the setpoint 2, it can be manual or
The setpoint option consists of a plug-in additional card that
once installed to the meter's main board, activates its own
programming module. The setpoints programming may be
locked out by means of DIP-switches located on the main
board to prevent from accidental or unauthorized changes.
The available alarm/setpoint output options are the following:
2RE: 2 SPDT relays rated 8A
4RE: 4 SPST relays rated 5A*
4OP: 4 isolated open-collector transistors NPN
4OPP: 4 isolated open-collector transistors PNP
These type of outputs, capable of carrying out a wide variety
of control operations and processing of limit values, increases
notably the unit's performance qualities thanks to the
possibility of combining basic alarm functions with advanced
safety and control applications.
