Example: You have set your set point 1 (Lo) at 6.00
µ
S and your hysteresis limit value is at 0.50
µ
S. If
your measured value undershoots the low set point of 6.00
µ
S, the controller’s relay activates, which in
turn activates an external device such as a pump or valve. The actions of the external device will cause
the value to rise above 6.00
µ
S. When the value has increased to 6.50
µ
S, the relay, and hence the
pump will switch off.
1) Follow directions in 7.5.3 to enter Control Relay mode.
2) Press the ENTER key. Scroll with the
∆∆
or
∇ ∇
keys until the upper
display shows the hysteresis (dead band) value and the lower display
shows “HYS”.
3)
Press the
∆∆
or
∇ ∇
keys to enter your hysteresis value for Set point
1 (Set point 2). Your controller will activate at the value you select. Note: All settings for SP1 and
SP2 are completely independent of each other.
4) Press the ENTER key to confirm your selection.
5)
Proceed to 7.5.5, or return to Measurement mode by pressing the
∆∆
and
∇ ∇
keys simultaneously
(escape).
NOTE: Please refer to Appendix 3 for a graphical representation of the Hysteresis.
7.3.5 Setting an on-delay time lag
You can set as time delay for each relay, which stops the relay from switching on the moment the set
point is exceeded. This controller lets you set a 0 to 1999 seconds time delay before the relay activates.
1) Follow directions in 7.5.4 to enter Control Relay mode.
2) Press the ENTER key. Scroll with the
∆∆
and
∇ ∇
keys until the
upper display shows “0” time and the lower display shows “On.d”.
3)
Press the
∆∆
or
∇ ∇
keys to enter on-delay time for Set point 1
(Set point 2). The controller will delay activation for the number of
seconds (0 to 1999) you select.
4) Press the ENTER key to confirm your selection.
5) Proceed to 7.5.6, or return to Measurement mode by pressing the
∆∆
and
∇ ∇
keys simultaneously
(escape).
7.3.6 Setting an off-delay time lag
You can set as time delay for each relay, which stops the relay from switching off the moment the value
reached the set point and hysteresis. This controller lets you set a 0 to 1999 seconds time delay before
your relay deactivates.
1) Follow directions in 7.5.5 to enter Control Relay mode.
2) Press the ENTER key. Scroll with the
∆∆
or
∇ ∇
keys until the
upper display shows “0” time and the lower display shows “OF.d”.
3)
Press the
∆∆
or
∇ ∇
keys to enter on-delay time for Set point 1
(Set point 2). Your controller will delay activation for the number of
seconds (0 to 1999) you select.
4)
Press the ENTER key to confirm your selection.
5) Continue with Advanced Set-up mode procedures, or return to Measurement mode by pressing
the
∆∆
and
∇ ∇
keys simultaneously (escape).
