Safety and warning hints This symbol inidcates passages in the text where you have to pay special attention so as to guarantee correct use and exclude any risk. This device is made and tested according to the valid standards of technics and has left the factory in a perfect safety state. To keep this state and secure operation without danger, the user has to observe the saftety and warning hints, contained in this operation manual. There is no galvanic separation of the inputs from the power supply. The device must be protected against accidential contact if it is not supplied from a SELV source (see EN 60 950). Assembling and mounting of electrical divices are restricted to be done by skilled electricians! Skilled electrician is, who can judge the tasks deputed to him and foresee possible dangers, due to his special education, knowledge and experience and consciousness of the pertinent standards. Mount devices are only allowed to be operated when mounted. Finger protection at connection part of mount devices is to be secured when mounting! While mounting the device, it must be secured that the requirements, which are asked for the device in the pertaining standards for safety, are not affected in a negative way, so reducing the safety of this mount device. Mounting and assembling of device needs observation of the specifications of the local Energy Suppliers. Before switching on, make sure that the power and control voltages are not exceeding the values in accordance with the technical data. If it is to be assumed that operation without danger is not further possible, the device must be put out of operation and secured from unintentional operation! It must be assumed that an operation without danger is not further possible, if the device shows damage, if the device stops functioning, after a longer stocking period under unfavourable conditions, after heavy strain during transportation. If by a failure or a malfunction of the device, endangering of men or animals or damaging of facilities are possible, this must be avoided by additional safety measures (end switches, protection devices and etc.). Before opening any cover, the device must be switched voltagefree. Hengstler Counters are intended for industrial applications. The mounting environment and nearby cabling have an important influence on the EMC (noise radiation and noise immunity) of the counter. When putting into operation, the EMC of the whole installation (unit) has to be secured. In particular, the relay outputs are to be protected from high noise radiation by suitable wiring. The range of applications for those products are industrial processes and controls, where the overvoltages applied to the product at the connection terminals are limited to values of the overvoltage category II. page 2/16 tico 742 2 742 021 Rev. 010399

Press E to scroll through the applicable choices for the currently displayed parameter Timing is interrupted while the unit is in program mode Changes become valid after returnal to control mode Operating Function: Determines how output 1 will operate in relation to the Preset 1. Choices are: On Delay (OndL), Off Delay (OFdL), Interval 1 (int1: must be sustained) Interval 2 (int2: Edge triggered; need not be sustained) On/Off Delay (OnOF), Delay/Interval (dint), Accumulative (ACC) A complete explanation, with timing diagrams, of each function can be found on page 9. out2 0 AbS Note: The following parameter will not appear if Operating Function is set to Off Delay, Delay/ Interval or On/Off Delay. In these instances Output 2 automatically defaults to Batch Count. Output 2 Operation: Determines the functionality of the 2nd output. Choices are: Preset 2 (): The unit will function as a dual setpoint timer, with output 2 linked to Preset 2. Batch Count (bc): Output 2 will be activated after a preset amount of Operations is completed. The preset value is input in the Batch count screen in Control Mode. Note: The following parameter will only appear if Output 2 is set to Preset 2. Preset 2 Operation: Determines how Preset 2 will operate in relation to Preset 1. The available choices vary based upon the selected Operating Function : For On-Delay and Accumulative: Absolute (AbS): Preset 2 is input as an absolute value, and the unit operates like two independent On-Delay timers. Prewarn (PrE): Preset 2 is set as a value relative to Preset 1. The input value for is equal to the amount of time that Output 2 will activate prior to Output1. Ex: If = 20 seconds, and equals 5, then output 2 will activate 15 seconds (20-5) after the timing cycle is initiated. For Interval 1 and Interval 2: Begin Together (bt): Preset 2 is set as an independent time interval which will begin timing and activate Output 2 upon initiation of the start signal. End Together (Et): Preset 2 is set as a value relative to Preset 1. The timing sequence for will initiate at the appropriate time so that the timing sequences for and will end simultaneously and Output 1 and Output 2 will deactivate together. Sequential (SE): Preset 2 is set as an inependent time interval which will begin its timing sequence upon completion of the interval. bct 0000 Note: The following parameter will only appear if Output 2 is set to Batch Count. Batch Count Output: Sets the duration of Output 2, within a range from 1 second to 9999 seconds. A setting of 0000 will latch the output until a reset signal is received. page 6/16 tico 742 2 742 021 Rev. 010399
trn 1 Time Range 1: Sets the unit of measure for the time values that will be used for Preset 1. The choices will not appear on the bottom display, but will be signified with the annunciator lights. Choices are: Seconds, Minutes, Hours, Minutes:Seconds, Hours:Minutes. dec 1 Note: The following parameter will not appear if Minutes:Seconds or Hours:Minutes is chosen for Time Range 1. Decimal Position for Time Range 1: Determines the resolution of the selected time range. Settable from 0000 to 0.000. trn 2 Note: The following parameter will only appear for those configurations that provide a Preset 2 display. Time Range 2: Sets the unit of measure for the time values that will be used for Preset 2. The choices will not appear on the bottom display, but will be signified with the annunciator lights. Choices are: Seconds, Minutes, Hours, Minutes:Seconds, Hours:Minutes. dec 2 Note: The following parameter willnot appear if Minutes:Seconds or Hours:Minutes is chosen for Time Range 2. Decimal Position for Time Range 2: Determines the resolution of the selected time range. Settable from 0000 to 0.000. tdir up Timing Direction: Determines whether the time values for Preset 1 and 2 will increment from zero and change the state of the output at the set value (up) or decrement from the set value and change the state of the output at zero (dn). PrSt On FrSt 0n Power Enable: After a loss of power, the unit can be either reset upon reapplication of power (0n) or continue from the point of power interruption (OFF). Front Panel : When active (On), the timing operation can be reset in Control Mode by simultaneously pressing the E and P keys. If inactive (OFF), the timing operation can only be reset through the remote input. SLuL 0 Security Level: 4 different levels of security are available: 0 = Full Access 1 = SP Locked Out 2 = Access to Program Mode only by holding the P key for 10 seconds. 3 = SP Locked Out and access to Program Mode only by holding the P Key for 10 seconds 2 742 021 Rev. 010399 tico 742 page 7/16
Programming Overview * If Delay/ Interval or On/ Off are selected as the Operating Function, Out2 is automatically set to Batch. However, the setting is still available, and the second time range is available ** For the Interval 1 & Interval 2 modes, a second time range will not appear if the Preset 2 operation is set to End Together. This is also true for the On Delay and Accumulative Modes if Prewarn is the selection for Preset 2 Operation. page 8/16 tico 742 2 742 021 Rev. 010399
