operations. On-
Off hysteresis prevents the output from “chattering” or making fast,
continual switches if the cycling above and below the set point occurs very rapidly.
Figure 8.1: Typical Relay operation
High type (H-ON):
For High type of set value, once process value reaches up to set point + Hysteresis
value, relay will be ON after few seconds (as per relay delay) and it will be ON until
process value goes down to Set point.
Low type (L-ON):
For Low type of set value, once process value reaches down to set point
– Hysteresis
value relay will be ON after nearly few seconds (as per relay delay) and it will be ON
until process value goes up toward Set point.
NOTE:-
LC5296-XP-DC is having only ON-OFF controlling so no need to do any additional
setting.
8. CALIBRATION PROCEDURE
8.1 Procedure for CAL-zero and CAL-span
The instrument is factory calibrated for the specified range, but due to long term
drift of components, re-calibration may be necessary in some cases. For
calibrating the instrument a reliable source is required. This source should be
at least ten times accurate compared to the range of the instrument.
The unit can be calibrated without opening it and without trimpots. To enter in
calibration mode press ‘ENT’ key consecutively in Run mode until
PASS
message on the display. Now pre
ss ‘INCREMENT KEY’ to enter the correct
password (Enter user’s password if selected or enter factory default password:
1), after entering the correct password,
TUNE/CONF
message is displayed,
now press ‘INCREMENT KEY’ to bring calibration mode. Invoking of Increment
key will show
CAL
message. Now press ‘ENT’, this will bring the first calibration
parameter on display as
AMB.
(Ambient in case of T/C), in case of RTD or
Linear Input it will show
CALZ.
(Zero calibration).
