Product Interface Points

Hand-Off-Auto (HOA) Switch

Each pump on the Check It has its own Hand-Off-Auto (HOA) selector switch. When set to “Hand” mode, the pump will enter hand mode, and the contactor output from the Check It will activate. When in the middle position, the pump will be in “Off” mode and will not activate during pump-starting events. When set to “Auto” mode, the pump will be used as the lead or lag pump as indicated by the Pump Selector Switch.

Pump Selector Switch:

This switch selects the lead/lag configuration of the pumps. If Pump One (P1, Left) or Pump Two (P2, Right) is selected, that pump will be the permanent lead pump. If “Alternate” (ALT, Middle) is selected, the pumps will alternate between lead and lag every run cycle.

Check It Button:

The Check It button on the chassis of the product is used to simulate start events. This can be used to verify pump connections and double-check that the pump HOA and Alternate configurations are behaving as expected. If the system does not start pumps or alternate between them as expected, double-check the HOA and Pump Lead Selector switches.

Introduction

Product Overview

• The Check It™ Duplex control panel is designed to operate two sewage pumps in demand dose applications. It supports both 120VAC and 230VAC pumps within specified FLA ranges and has a Type 4X (indoor/outdoor) enclosure.

• The panel offers up to five float inputs: low level alarm, stop level, lead level, lag level or lag/alarm level, and high alarm or high alarm/start level. The pump starts when the liquid level rises and activates the pump lead switch, and runs until the pump stop switch is deactivated, ending the cycle. If the pump lag level alarm switch is
  activated, the second pump will start and both pumps will continue to run until the pump stop switch is
  deactivated. After the pump stop switch is deactivated, the system will alternate the lead pump if the Pump Lead Selector Switch is set to ALT. The lag and alarm inputs can both be programmed as lag/alarm inputs to trigger an alarm when the lag pump starts.

• If the low level float deactivates, a low level alarm will be triggered and both pumps will turn off.

Description of Product Interface

The following sections will describe all of the interface points with the Check It™, including all buttons, indicator outputs, and sensor inputs for the system.
Outside of the Panel

Each Check It™ panel is equipped with a test/silence switch, an Red-Green (RG) indicator LED, and a buzzer. The test/silence switch is used to activate an indicator test routine to verify the beacon, buzzer, and LED indicators are all functioning properly. The Red-Green beacon will by default be illuminated green while the system is normal and monitoring, will blink green while a pump is running, and will blink red when there is an alarm. If both an alarm and a pump run event are happening simultaneously, the beacon will alternate between Red and Green. If there are no pumps enabled (both are set to OFF mode), the beacon will blink a yellow warning to the user.

Inside the Panel

HOA Switches

• Each pump on the Check It™ has its own Hand-Off-Auto (HOA) selector switch. When set all the way up, the pump will enter hand mode and the contactor output from the Check It™ will activate. When in the middle, the pump will be in OFF mode and will not activate during pump starting events. When set all the way down, the pump will be in auto mode and will be used as the lead or lag pump as indicated by the Pump Selector Switch. Note that if both pumps are set to OFF, the RG beacon will blink yellow to warn the user that the system will be unable to activate any pumps.

Pump Selector Switch

• This switch selects the lead/lag configuration of the pumps. If Pump One (P1, Left) or Pump Two (P2, Right) are selected, that pump will be the permanent lead pump. If Alternate (ALT, Middle) is selected, the pumps will alternate between lead and lag every run cycle.

Check It™ Button

• The Check It™ button on the chassis of the product is used to simulate start float events. This can be used to verify pump connections and double check that the pump HOA and Alternate configurations are behaving as expected. If the system does not start pumps or alternate between them as expected, double check the HOA and Pump Lead Selector switches.

Test/Config Button

• The Test/Config button is used to activate the indicator test routine, to clear active alarms, and the modify the system settings. See the “How To Clear an Alarm” section for details on alarm clearing and the “How to View and Change Settings” section for details on configuring the device.

Indicator LEDs

• The Check It™ features indicator LEDs for each sensor input as well as indicator LEDs for each pump. The F1 through F5 LEDs indicate the state of the float inputs. the S1 and S2 LEDs indicate if the seal fail sensor inputs are tripped or not. The Pump 1 Run and Pump 2 Run LEDs indicate whether or not their respective pumps are running. Note that if a Pump Run LED is blinking, that means that pump’s seal fail sensor has been tripped.

Auxiliary Dry Contact

• The Check It™ features a single auxiliary dry contact alarm output with both normally open and normally closed connections. This dry contact output will activate during any alarm condition. Additionally, the contact will be active when the product loses power, allowing for power loss detection and alarming when connected to building automation systems.

Sensor Connections

Float Sensors

• The F1 through F5 inputs are designed for standard signal level gold contact floats. They are powered by an isolated 3.3 Volt low power and touch safe power source generated by the Check It™ circuit board.

Seal Fail Sensors

• The S1 and S2 inputs are water detecting probe circuits designed for use with stainless steel pump seal fail probes. They are powered by an isolated 12 Volt alternating, low power and touch safe power source generated by the Check It™ circuit board. Next to the seal fail sensor inputs, there is a “SEAL SENSITIVITY” adjustment potentiometer. This can be used to adjust the trip point of the seal fail probes between 10 and 100 Kilo-Ohms of equivalent resistance through water. 100 K is the most sensitive setting, and 10 K is the least sensitive.

How To Clear an Alarm

• If automatic alarm reset is disabled, the user must manually clear all alarm events. To do this, activate and hold the Test/Silence switch on the side of the panel or the Test/Config button on the product chassis for 5 seconds. This will reset all active alarms.
• Note that if the alarm immediately re-activates and the buzzer activates again, this means that the alarm condition is still present and the system cannot clear the alarm. If this happens, check for the source of the alarm.

Settings

• The Check It™ panel has several settings that the user can use to customize the panel for the application. This section will describe how to change the settings and provide a list of the available settings.

How to View and Change Settings

• Press and hold the test/configure pushbutton on the Check It™ chassis to begin the setting viewing and changing routine. The system will immediately begin a test blinking pattern of all indicator outputs. After holding for 5 seconds, the setting viewing and changing routine will begin. The routine is as follows:

1. LED Test Pattern; Press and hold the Test/Config button.
   • The LED indicator outputs, buzzer, and beacon will all begin blinking in a test pattern.
2. View Settings; Hold the Test/Config button for 5 seconds.
   • The test blinking pattern will stop and the indicator LEDs will display the current system settings.
   • If an indicator LED is ON, that means the setting is enabled. Otherwise, the setting is disabled.
   • See the “Available Settings” section for a summary of the configs and which LED they are indicated by.
3. Toggle Settings; Hold the Test/Config button for another 5 seconds to change a setting.
   • A fast blinking pattern will begin to move through the indicator LEDs from left to right and then up to the green beacon.
   • This fast blinking pattern indicates which setting is currently selected.
   • To toggle a setting, release the Test/Config button while the desired Setting Indicator LED is blinking.
   • After releasing the Test/Config button, a medium blinking pattern will confirm which setting was toggled, after which the system will display the new system settings followed by a burst of fast blinks before the system returns to normal operation..
4. Exit   Without Saving; To exit without changing any settings, keep holding the Test/Config button until the fast blinking pattern moves through all of the indicator LEDs and the system returns to the test blinking pattern. The Test/Config button can now be released without changing any settings.

Automatic Low-Alarm Enable

The low alarm input of the Check It™ is disabled by default to remove the need for installing jumpers on panels that do not use it. However, the system will automatically enable this input if it detects a closed float connected to it for at least 30 seconds.
