While the counter's built-in memory protection circuit can retain values for power failures lasting up to 10 minutes, the optional battery protects memory in case of a longer power outage. We recommend using the battery as a safeguard. Memory values can be retained for up to 5 years.

Firmly push the switches to avoid having two numbers appear in the display window. This causes the operating time to drift widely. WARNING Undesirable settings 530 counts? 2530 counts? 3530 counts? Do not change the setting while the counter is powered up. It may cause a momentary output to occur. 9 Do not set all four digits to zero. This causes a momentary output to occur that may lead to accidental injury or damage. H7CN H7CN Mounting PANEL MOUNTING Using Y92F-30 Adapter Insert the counter through the panel cutout. Push the Y92F-30 adapter from the rear of the counter as far forward toward the panel as possible. Push the P3G- socket onto the rear of the counter. Then wire the socket. Tighten the two retaining screws. To release the adapter, lift the tab at the rear of the adapter. Several counters may be panel mounted close together using a Y92F-30 adapter as shown here. When mounting two or more counters in a vertical line, arrange the adapters so that their molded tabs are positioned on the right and left sides. When mounting two or more counters in a horizontal line, arrange the adapters so that their molded tabs are positioned on the top and bottom sides. Panel cutout for side-by-side mounting of two counters Molded tab Molded tab P2CF- Socket Mounting The P2CF- socket has two hooks that secure the counter to the socket. Be sure to allow at least 20 mm (0.79 in) clearance above and below the socket to gain access and to release the hooks for servicing and maintenance. Insert counter into the socket. Latch hooks. Then clip rear of the socket to the track. Push the bottom onto the track until the latch hooks securely. Removal Pull the latch on the socket with a flatblade screwdriver and remove the counter and socket as one unit. NOTE: DIMENSIONS ARE SHOWN IN MILLIMETERS.
