Kits and options

Optional Character Reference – 16, 26 and DF Series Only
Available on Series 26, 26M and DF controls(Normally closed pushbutton across reset terminals. Pushbutton ordered separately):
Manual reset only applies to the function associated with terminal LLCO. When theliquid rises to the electrode on terminal LLCO, the control will remain de-energized(load contacts in original state) until the pushbutton is depressed. The control willthen energize, (LED will be lit) changing the state of the contacts. The control
remains energized until the liquid level recedes below electrode on terminal LLCO.
The control then de-energizes, (LED will go off) returning load contacts to their
original state. Unless otherwise specified, there is a three second time delay on
decreasing level. Liquid must be below probe on terminal LLCO for full three seconds
before control de-energizes.

Manual Reset with Power Outage Feature•G

Available on Series 26, 26M, and DF controls
Reset (Normally closed pushbutton across reset terminals. Pushbutton orderedseparately) Control will ignore power loss to control. With liquid in contact withelectrode on terminal LLCO, a power outage will cause the control to de-energize, butwill automatically energize upon return of power. However, loss of liquid will causecontrol to de-energize and remain so until liquid again rises
to electrode and pushbutton is depressed.

Time Delays Associated with Terminals H and L

Available on Series 16, 16M, and DF controls
With time delay on increasing level, the liquid must be in contact with the highelectrode for the full duration of the time delay before control will operate. With delayon decreasing level, the liquid must be below the low electrode for the full durationof the time delay before control will operate. In single level service, terminals 3 and 4
must be jumpered together to achieve time delays on both increasing and decreasinglevels or just decreasing level.

Time Delays Associated with Terminal LLCO
Available on Series 26, 26M, and DF controls
3 Second time delay on decreasing level is standard. Delayup to 90 seconds, can be specified and would act in the samemanner as listed above.

Chart B – Optional Character Information

Time Out Option

ResetFunction

Available on Series 16, 16M, and DF controls
The latching circuit for the high and low electrode hasan optional timer. In some applications the High or Low
electrode may become short circuited or disconnected. Suchan occurrence may potentially over fill in fill applications,or cause the pump to run dry in pump down applications.
The time option is custom programmed up to 3 minutes.
When a fault condition occurs, the FILL LED will have a blinksequence of .5 seconds on 2 seconds off. See Chart A fortime delay options.

Test Feature

Available on Series 26, 26M, and DF controls
Allows LLCO circuit to be tested. Holding down the reset
button for 3 seconds will allow the LLCO circuit to trip which
simulates the loss of water, without the need of draining
the water level in the boiler. The control will return to normal
operation once the reset button is pressed a second
time. (Test feature option only available with the manual resetfunction.)
