ICM Controls ICM455 General instructions

ICM455
Important Safety Information
HIGH VOLTAGE WARNING! – Turn off power at the
main service panel before installing.
Programmable,
Three-Phase
Voltage Monitor
Phase Unbalance Protection
• Voltage Unbalance: 2-20%, adjustable
Over/Under Voltage
• Under Voltage: 2-25%, adjustable
• Over Voltage: 2-25%, adjustable
Phase Loss Protection
• Phase Loss Condition: Equals 25% of nominal for any given phase; system will
shut down and a fault will be recorded if this should occur.
Delay on Break Timer
• Control Voltage: 18-240 VAC
• Time Delay: 15 seconds to 10 minutes
Fault Interrogation Delay
• Time Delay: 0 – 15 seconds, adjustable
• Provides a delay between fault detection and system shutdown—helps to eliminate
nuisance trips and unnecessary shutdowns.
Parameters
Installation
1.Turnoffpoweratmainservicepanel.
2.Usingtwo(2)#8screws,mounttheICM455inacool,dry,easilyaccessible
locationinthecontrolpanel.
3.Connectvoltageasshownin“WiringDiagram”.Leaveexistinglineandloadside
connectionsintactonthecontactor.
4.Loadsidemonitoringisoptional(unitmaybeusedtomonitorlinesideonly).Wire
thecontactorandoptionalcontrolvoltagemonitorasshownin“SystemDiagram”.
Note:Load/line wire must be rated for 3-phase voltage rating, 20ga minimum.
5.Uponapplicationofpower,theICM455willbeonlineandwillbegintomonitor
thesystem.
 Note:If voltage is not correct, see “Voltage Read Calibration” in Button
Functions section
• Terminals3and4arethecontrolsignalinputterminals.
• “ControlMode”isturnedONorOFFinsetup.
• With“ControlMode”settoON,theremustbeavoltagepresentonterminals3
and4fortherelayoutputterminals1and3toclose;thisvoltagecanbesupplied
fromathermostat,pressureswitch,etc.
• Whenthevoltageonthesesterminalsisre-applied,theunitwillnotre-energize
untilthedelayonbreak(0-10minutes)timehaselapsed.
• Useofterminals3and4isoptional;theywillbeignoredifthe“ControlMode”is
switchedtoOFF.
• Terminals1and3are“dry”,normallyopencontacts.
• Terminals1and3areclosedwhenpoweriswithinspecications.
• Terminals1and3openwhenthereisafaultcondition.
• Terminals1and3openwhenthereisalossofthecontrolsignalwith“Control
Mode”settoON.
• Auxiliaryterminalswillbeusedinfuturemodels.
Setting the Parameters
1.PressthegreenSETUPbuttontoenterthesetupmode.SetupLEDwilllight.
2.Usethe and buttonstochangeuserparameters.
3.ScrollthroughsetupbypressingandreleasingtheSETUPbutton.
4.Whenthelastparameterhasbeenset,thephaseaveragewillbedisplayedand
thesetupLEDwillautomaticallyturnoff.
